I'd like to capture all output and errors when installing a packages. The steps when installing a package, however, do not seem to be captured by the sink() command. Here's an example:
A main.R file:
fp <- file("test.log", open = 'wt')sink(fp, type = 'output')sink(fp, type = 'message')install.packages("stringr")sink(type = 'message')sink()Using R -q -f main.R to run the file, I see the following in my console:
-> % R -q -f main.R> fp <- file("test.log", open = 'wt')> sink(fp, type = 'output')> sink(fp, type = 'message')> install.packages("stringr")* installing *source* package ‘stringr’ ...** package ‘stringr’ successfully unpacked and MD5 sums checked** using staged installation** R** data*** moving datasets to lazyload DB** inst** byte-compile and prepare package for lazy loading** help*** installing help indices*** copying figures** building package indices** installing vignettes** testing if installed package can be loaded from temporary location** testing if installed package can be loaded from final location** testing if installed package keeps a record of temporary installation path* DONE (stringr)> sink(type = 'message')> sink()>The contents of test.log:
