The plotRuns method finds these connections between executions to determine the executions that comprise a processing workflow.

## S4 method for signature 'Recordr'
plotRuns(recordr, id = as.character(NA),
  file = as.character(NA), start = as.character(NA),

error

The text of error message to match.
seq

The sequence number for a run. #' @param id The execution identifier of a run to view
orderBy

direction

The direction to trace the lineage, either fowward, backward, or both. The default is both
quiet

A logical if TRUE then output is not printed.

Details

If the run id or seq number is know for the run to be traced, then one or the other of these values can be used. Alternatively, other run attributes can be used to determine the run to be traced, such as file, start, etc. If these other search parameters are used and multiple runs are selected, only the first run selected will be traced. These search parameters can be used together to easily find certain runs, for example, the latest run of a particular script, the latest run with a specified tag specified, etc. (see examples).

Value

A list of the execution identifiers that are in the processing workflow.

Description

The R package recordr provides methods to easily record data provenance about R script executions, such as the files that were read and written by the script, along with information about the execution, such as start time end time, the R modules loaded during the execution, etc. This provenance information along with any files created by the script can then be combined into a data package and uploaded to a data repository such as DataONE.

Capture, review and publish data provenance

Description

The Recordr class provides methods to record, search, review and publish data provenance about R script executions. Information about files read and written by a script and the execution environment can be captured for each script execution. Script executions can then be reviewed and selected to be published to the DataONE data repository, by retrieving archived copies of the R script, the files read and written by a script and a description of the provenance relationships between objects in the run, which are then combined into a package and uploaded to the requested member node.

Slots

recordrDir

value of type "character" containing a path to the Recordr working directory

dbConn

A value of type "SQLiteConnection" that contains the connection of the recordr database

dbFile

A valof of type "character" that contains the location of the recordr database file

Methods

  • initialize: Initialize a Recordr object

  • startRecord: Begin recording provenance for an R session

  • endRecord: Get the Identifiers of Package Members

  • record: Get the data content of a specified data object

  • listRuns: Output a list of recorded runs to the console

  • viewRuns: Record relationships of objects in a DataPackage

  • deleteRuns: Record derivation relationships between objects in a DataPackage

  • publishRun: Upload all objects associated with a run to a repository

  • traceRuns: Trace processing lineage by finding related executions.

  • plotRuns: Trace processing lineage for a run and plot it.

  script = as.character(NA), startTime = as.character(NA),
  endTime = as.character(NA), tag = as.character(NA),
  errorMessage = as.character(NA), seq = as.integer(NA),
  orderBy = "-startTime", delete = FALSE)

Arguments

recordr

A Recordr instance
...

additional parameters
runId

An execution identifiers
script

The flle name of script to match.
startTime

Match executions that started after this time (inclusive)
endTime

Match executions that ended before this time (inclusive)
tag

The text of tag to match.
errorMessage

The text of error message to match.
seq

The run sequence number
orderBy

The column that will be used to sort the output. This can include a minus sign before the name, e.g. -startTime
delete

Details

This method is used internally by the recordr package.

Value

A data.frame that contains execution metadata for executions that matched the search criteria

Standardise a function call

Description

Begin recording provenance for an R session.

Description

This method starts the recording process and the method endRecord() completes it.

Usage

startRecord(recordr, ...)

## S4 method for signature 'Recordr'
startRecord(recordr, tag = as.character(NA),
  .file = as.character(NA), .console = TRUE, log = as.character(NA))

Arguments

recordr

a Recordr instance
...

additional parameters
tag

a string that is associated with this run
.file

the filename for the script to run (only used internally when startRecord() is called from record())
.console

a logical argument that is used internally by the recordr package
log

A character string. If .console=TRUE, the file to log console commands to. The default is 'console.log'.

Details

The startRecord() method can be called from the R console to begin a recording session during which provenance is captured for any functions that are inspected by Recordr. This recordr session can be closed by calling the endRecord() method. When the record() function is called to record a script, the startRecord() function is called automatically.

Value

execution identifier that uniquely identifies this recorded session

See Also

Recordr class description

Examples

## Not run: 
rc <- new("Recordr")
startRecord(rc, tag="my first console run")
x <- read.csv(file="./test.csv")
runIdentifier <- endRecord(rc)

## End(Not run)

Trace processing lineage by finding related executions

Description

A data processing workflow might include multiple processing steps, with each step being performed by a separate R script. These multiple steps are linked by the files that one step writes and the next step in the workflow reads. The traceRuns method finds these connections between executions to determine the executions that comprise a processing workflow, and returns information for each run in the processing workflow including all files that were read and written by each script.

Usage

traceRuns(recordr, ...)

## S4 method for signature 'Recordr'
traceRuns(recordr, id = as.character(NA),
  file = as.character(NA), start = as.character(NA),
  end = as.character(NA), tag = as.character(NA),
  error = as.character(NA), seq = as.character(NA),
  orderBy = "-startTime", direction = "both", quiet = TRUE, ...)

Arguments

recordr

a Recordr instance
...

additional parameters
id

The identifier for a run. Either id or seq can be specified, not both.
file

The name of script to match
start

Match runs that started in this time range (inclusive) Times must be entered in the form 'YYYY-MM-DD HH:MM:SS' but can be shortened to not less that "YYYY"
end

Match runs that ended in this time range (inclusive) Times must be entered in the form 'YYYY-MM-DD HH:MM:SS' but can be shortened to not less that "YYYY"
tag

The text of tag to match
error

The text of error message to match.
seq

The sequence number for a run. #' @param id The execution identifier of a run to view
orderBy

Sort the results according to the specified column. A hypen ('-') prepended to the column name denoes a descending sort. The default value is "-startTime"
direction

The direction to trace the lineage, either fowward, backward, or both. The default is both
quiet

A logical if TRUE then output is not printed.

Details

If the run id or seq number is know for the run to be traced, then one or the other of these values can be used. Alternatively, other run attributes can be used to determine the run to be traced, such as file, start, etc. If these other search parameters are used and multiple runs are selected, only the first run selected will be traced. These search parameters can be used together to easily find certain runs, for example, the latest run of a particular script, the latest run with a specified tag specified, etc. (see examples).

Value

A list of the execution identifiers that are in the processing workflow.

Examples

## Not run: 
# Trace lineage for the run with sequence number '101'
linkedRuns <- traceRuns(recordr, seq=101)

linkedRuns <- traceRuns(recordr, file="runModel.R", orderBy="-startTime")
# Trace lineage for the last execution with the tag 'best run yet!' specified.
linkedRuns <- traceRuns(recordr, tag="best run yet!", orderBy="-startTime")

Details

Saved execution metadata is typically first stored when an execution begins, then updated at the end of a run (with error messages and ending time, for example). Also, excution can be updated when a run is published, with information about the publishing process.

The list that is returned from "viewRuns" contains two elements - a data.frame with the execution information, and a data.frame that contains file information.
