I guess what you want is:
--8<---------------cut here---------------start------------->8---
(let* ((out (assoc-ref outputs "out"))
(out/bin (string-append out "/bin")))
(mkdir out/bin)
(copy-file "inst/bin/r"
(string-append out/bin "/r"))))))))
--8<---------------cut here---------------end--------------->8---
And I would write,
(lambda _
(mkdir (string-append #$output "/bin"))
(copy-file "inst/bin/r"
(string-append #$output "/bin/r")))
Well, using one or the other, I get:
--8<---------------cut here---------------start------------->8---
$ guix shell -L /tmp/foo r-littler -C -- r --help
Usage: r [options] [-|file]
Launch GNU R to execute the R commands supplied in the specified file, or
from stdin if '-' is used. Suitable for so-called shebang '#!/'-line scripts.
Options:
-h, --help Give this help list
--usage Give a short usage message
-V, --version Show the version number
-v, --vanilla Pass the '--vanilla' option to R
-t, --rtemp Use per-session temporary directory as R does
-i, --interactive Let interactive() return 'true' rather than 'false'
-q, --quick Skip autoload / delayed assign of default libraries
-p, --verbose Print the value of expressions to the console
-l, --packages list Load the R packages from the comma-separated 'list'
-d, --datastdin Prepend command to load 'X' as csv from stdin
-L, --libpath dir Add directory to library path via '.libPaths(dir)'
-e, --eval expr Let R evaluate 'expr'
--8<---------------cut here---------------end--------------->8---
Hope that helps,
