package requirements for Linux users

[jeanetteclark]

Feedback from Bryan Brasher:

I noted there were a few times that I fell behind when installing packages due to issues I had with running R on a Debian linux distro.

I found that for the packages we needed for class, that i needed to have the following linux packages installed:
libssl-dev
libcurl4-openssl-dev
libxml2-dev
libnetcdf-dev
libgeos-dev

For the next training, when we send the preparation email we should ask Linux users to contact us directly to try to get ahead of these linux package install issues

👍. Just FYI: There's a WIP but still very useful package and API for automating this.

For example, a call to https://sysreqs.r-hub.io/pkg/ncdf4 gives libnetcdf-dev.
