[R] Time for a companion mailing list for R packages?

[Avi Gross]

Respectfully, this forum gets lots of questions that include non-base R components and especially packages in the tidyverse. Like it or not, the extended R language is far more useful and interesting for many people and especially those who do not wish to constantly reinvent the wheel.
And repeatedly, we get people reminding (and sometimes chiding) others for daring to post questions or supply answers on what they see as a pure R list. They have a point.
Yes, there are other places (many not being mailing lists like this one) where we can direct the questions but why can't there be an official mailing list alongside this one specifically focused on helping or just discussing R issues related partially to the use of packages. I don't mean for people making a package to share, just users who may be searching for an appropriate package or using a common package, especially the ones in the tidyverse that are NOT GOING AWAY just because some purists ...
I prefer a diverse set of ways to do things and base R is NOT enough for me, nor frankly is R with all packages included as I find other languages suit my needs at times for doing various things. If this group is for purists, fine. Can we have another for the rest of us? Live and let live.

Someone is sure to point out that this isn't an RStudio support list, 
but your issue is with R, not with RStudio.  You created the table in 
f1, but you never returned it.  The variable f_table is local to the 
function.  You'd need the following code to do what you want:

f1 <- function(indata , subgrp1){
  subgrp1 <- enquo(subgrp1)
  indata0 <- indata
  temp    <- indata0 %>% select(!!subgrp1) %>% arrange(!!subgrp1) %>%
    group_by(!!subgrp1) %>%
    mutate(numbering =row_number(), max=max(numbering))
  view(temp)
  f_table <- table(temp$Species)
  view(f_table)
  f_table
}

f_table <- f1(iris, Species)

It's not so easy to also make temp available.  You can do it with 
assign(), but I think you'd be better off splitting f1 into two 
functions, one to create temp, and one to create f_table.
