[R] question

[Bert Gunter]

1. RStudio is not R; it is a separate for profit organization/company
that contributes free packages to R and also provides both free and
non-free R-oriented software. RStudio.com is their website (as you
know) and https://community.rstudio.com/# is where you can post
questions about *their* products.

2. HOWEVER... your query seems to be related to a special (not
standard) R package, not RStudio, specifically the 'flowr' package.
This general r-help list is not usually a good place to post queries
about such specific packages -- there are thousands of them! Maybe you
will get lucky and someone here will be able to help you.  But it is
recommended in the posting guide (linked below) that a better option
is to contact the package maintainer, which you can find via the:

maintainer("flowr")

command at the R console prompt.

Hope this helps.
