In ProvTools/provDebugR: A Time-Travelling Debugger

debug.view displays the contents of each file or variable queried. For snapshots or files with the file extension of .csv or .txt, the data will be loaded into the debugger environment before it is viewed. Otherwise, the data will be viewed using the system's default program for that type of file.

Additionally, a data frame showing what the function has opened will be returned, which contains the following columns: name The name of the variable or file being viewed. startLine The line number the variable or file is associated with. scriptNum The script number the variable or file is associated with. scriptName The name of the script the variable or file is associated with. title The title of the variable or file when viewed. notes Will display PARTIAL if the variable is a partial snapshot, or indicate that the provenance directory or a file is not found. NA otherwise.

Usage

The function signature for debug.view is:

debug.view(..., start.line = "all", script.num = "all")

The parameters of this function are: ... The variable names or file names to be queried. start.line The line number of the queried variables or files. * script.num The script number of the queried variables or files.

This function may be called only after initialising the debugger using either prov.debug, prov.debug.run, or prov.debug.file. For example:

prov.debug.run("myScript.R")
debug.view()
debug.view(x)
debug.view("x", y, start.line = 5, script.num = 2)
