Static code analysis for R currently allowing one to analyze code for clone detection and naming conventions.
With devtools package:
devtools::install_github("ecos-umons/extractoR")
You might need to adjust size of the stack if you want to analyze very huge number of lines of code. Do this both for R and your OS. This is known to happen when analyzing code from CRAN cape package.
For R it can be done such as:
options(expressions=10000)For GNU/Linux (and possibly other UNIX like OS) it can be done using ulimit:
# Current limit
ulimit -s
# Change it to a value sufficient to analyze CRAN cape package
ulimit -s 16384
