How to print the version of r in bash chunk?-CodePudding

I need to print my r version in a bash chunk in an r markdown file. In my terminal, I can print the version using "R --version" but when I try that command in bash I get the following error "R: command not found." When I use commands like git --version in the bash shell it works normally. Does anyone have any idea why the R --version code is different?

Thank you!

R -e 'cat(sessionInfo()$R.version$version.string, "\n")'

You might be able to try this:

$(type R | grep -o '/.*') --version

type will get you to the correct R version, grep will extract the path, and then you can pass the --version flag to get the R chunk.

Terminal output:

$ $(type R | grep -o '/.*') --version
R version 4.1.0 (2021-05-18) -- "Camp Pontanezen"
