"# install.packages" ? #14
Description

- The # is the R comment character. It’s just a note on the code to to install devtools (or remotes) in R if you run the install code and find that you don’t have devtools installed yet. You usually need command like tools like make to install devtools. I googled it and it looks like you can install R on a raspberry pi, but I don’t know anything about it. It does look like there might be some problems with Rccp, which is required for interacting with magick. You’ll also have to install magick manually if you aren’t using Mac or Windows (I haven’t included instructions because Linux users are good at trouble-shooting).

My Pi is an old 32-bit version, but with the latest Debian Buster (Raspbian). Lots of things claim they run on it, but they don't. Probably more chance with a 64-bit Pi.
So I went to the other extreme from the Raspberry Pi, and tried installing on my serious Arch Linux box. Under ten minutes each for R and devtools, and less for webmorphR. No obvious problems, everything finished without error, and the only warnings were:
stri_container_listraw.cpp:63:41: warning: argument 1 value ‘18446744073709551615’ exceeds maximum object size 9223372036854775807And:

Looks like your "hello world" type test uses your "demo stimulus files or functions that require python and dlib..."
I installed dlib, but R couldn't find a python package - seems odd. I tried install.packages("reticulate") which supposedly links R to any other python on my system. But I still get:
> devtools::install_github("debruine/webmorphR.dlib") Downloading GitHub repo debruine/webmorphR.dlib@HEAD Error in utils::download.file(url, path, method = method, quiet = quiet, : download from 'https://api.github.com/repos/debruine/webmorphR.dlib/tarball/HEAD' failed > devtools::install_github("debruine/webmorphR.stim") Downloading GitHub repo debruine/webmorphR.stim@HEAD Error in utils::download.file(url, path, method = method, quiet = quiet, : download from 'https://api.github.com/repos/debruine/webmorphR.stim/tarball/HEAD' failedMaybe if it wasn't "quiet" it wwould show what happens to the download? Can I turn that off somewhere?
I do have imagemagick-7.1.0.35-1 from the Arch repo. It says, "(2/2) Warn about old perl modules"...
Not your responsibility to teach me R, but I'm curious if any suggestions pop into your mind.
