In andrie/version.compare: Compares the Results of Running Code in Different Installed Versions of R

# Find installed versions of Rscript

rversion <- paste(R.version$major, R.version$minor, sep = ".")
rscript <- findRscript(version = rversion)

# Configure which installed version to use

# Compute vector mean in different R installations

version.time(rscript, {

})


# Compute matrix cross product in different R installations

version.time(rscript, {
