func |
Function object to call in the new R process.

args |
Arguments to pass to the function. Must be a list. |
libpath |
The library path. |
repos |
The |
cmdargs |
Command line arguments to pass to the R process.
Note that |
system_profile |

callr
makes a copy of the user's .Renviron
file and potentially of
the local or user .Rprofile
, in the session temporary
directory. Avoid storing sensitive information such as passwords, in
your environment file or your profile, otherwise this information will
get scattered in various files, at least temporarily, until the
subprocess finishes. You can use the keyring package to avoid passwords
in plain files.
Other callr functions:
r_vanilla()
