aaarg, sang too quickly. I saved the script by @jake
root_dir <- thisfile() %>%
str_replace(pattern = "/code/test.R", replacement = "")
into a file called
test.R, and tried to run it, using
Rscript, but the output was just
which fair enough if you consider the documentation. So one of the ways referenced in the documentation to get the full path is to source the file, so this will work:
R cmd -e "source('test.R')"

But of course, it only works if you are already in the working directory!! Which you could express explicitly… but…
if(Sys.info()["nodename"]… is as good as it gets? Or maybe setting the variable from linux. In fact, I’m writing a blog post about how to accomplish this using linux services… and there you can set up the path explicitly, which at least helps the automated run scenario… and perhaps for all other cases,
here is enough?
