liblog

This package logs calls to loadNamespace, so one can track thei use of packages.

Install with:

remotes::install_github("moodymudskipper/liblog")

Suggested use

Edit your R profile, (you can run file.edit(file.path(R.home(), "etc", "RProfile.site"))) and add the following line at the end :

liblog::use_liblog()

It will display the following message each time you start R:

Tracing function “loadNamespace” in package “base” to log loaded namespaces in ‘C:/PROGRA_1/R/R-361.2/loadNamespace.log’

The actual path will change depending on your system.

If you’d rather do it silently, use liblog::use_liblog(verbose = FALSE) instead.

From there on, each time a package has its namespace loaded (not only attached!), a new line will be added to the file mentionned in the message, you can get this path by calling getOption("liblog.path") and you can choose another path by adding a call to options() before use_liblog() call in your RProfile so you’ll have:

options(liblog.path = your_path)
liblog::use_liblog()

Test it!

Apply the steps above, restart R (in RStudio : ctrl + shift + F10), then see what’s been logged already by calling :

file.edit(getOption("liblog.path"))

Duplicates are present because loadNamespace() is really called several times on some packages.

More conveniently, you can call liblog::get_liblog(), which by default removes duplicate records and ignores base and recommended packages.

Is that it ?

For now it is, after I’ve used it for some time I think I’ll implement some visualization functions wrapped on get_liblog(). Maybe I’ll also need some options or utilisties to flush or archive the log, or warn about it getting too big, but I need data first! (or feedback, wink wink => POST ISSUES AND HELP ME HELP YOU!).
