A Time-Travelling Debugger.
provDebugR
A debugging tool that leverages provenance to provide handy information about R scripts to assist in writing them.
For a more in-depth description of the functions available in this package please refer to the Wiki.
Installation
Version 3.5.0 or later of R is required.
Devtools is needed for installation:
install.packages("devtools")
Installation of all required packages (can be copied and pasted):
install.packages("provParseR")
install.packages("provGraphR")
install.packages("rdtLite")
devtools::install_github("End-to-end-provenance/provDebugR")
provDebugR also imports:
- httr
- igraph
- jsonlite
- methods
- testthat
- textutils
Once installed, load provDebugR by calling:
library("provDebugR")
Usage
To initialise the debugger with a script, call:
prov.debug.run("scriptName.R", snapshot.size = 100)
Alternatively, if you just called rdtLite's prov.run function, you can call:
prov.debug()
Lastly, if you have the PROV-JSON provenance file, you can also call:
prov.debug.file("provJsonFileName.json")
Once the debugger has been initialised, the rest of the functions the package provides can be used.
