[R] the opposite of pluck() in purrr

[Bert Gunter]

tidyverse is an RStudio ecosystem of packages -- it is not part of R's
"standard" package distro, so as the posting guide linked below says:

"For questions about functions in standard packages distributed with R (see
the FAQ Add-on packages in R
<https://cran.r-project.org/doc/FAQ/R-FAQ.html#Add-on-packages-in-R>), ask
questions on R-help.
If the question relates to a *contributed package* , e.g., one downloaded
from CRAN, try contacting the package maintainer first. You can also use
find("functionname") and packageDescription("packagename") to find this
information. *Only* send such questions to R-help or R-devel if you get no
reply or need further assistance. This applies to both requests for help
and to bug reports."

While you may nevertheless get lucky here, a better bet is to post on
RStudio's own forum, set up specifically to provide such help:
https://community.rstudio.com/

Cheers,

Bert Gunter
