add simple R example

Wouldn't it make more sense to rely on the r docker container here instead of installing?

@bstabler given your +1 to Chris's comment, are you going to switch to a container approach? If not, I'll close this for now.

[bstabler]

I think both examples are useful. How about I (or someone else) add a docker version as well?

[vtbassmatt]

The templates are intended to show the canonical / most common way, not to provide options. A pattern we've used before is to keep the template simple but point to a language guide in our docs (for example, Python) that goes into more detail. We take doc PRs in another repo if that's a line you want to pursue.

I updated the example to use the R docker container, thanks.

Why have you removed the R package installation example? I think it could be pretty informative and also, everyone will want to install packages. I am struggling at the moment to get R package installed in the pipeline. I checked rocker-org/rocker-versioned#108 and then tried to make the folder 777, but I did not have sufficient permission.

Hi,

If you're looking for an example for installing packages, I'd suggest adopting the same approach as is in the rocker images (using install2.r from Dirk's littler library). For example, from the tidyverse container in rocker:

install2.r --error \
    --deps TRUE \
    tidyverse \
    dplyr \
    devtools \
    formatR \
    remotes \
    selectr \
    caTools \
    BiocManager

Hey all. We don't have an R expert or champ internal to the team. Does the PR as it currently exists look good? If a couple of you want to give me a thumbs-up, I'll be happy to merge it. Otherwise, I'm going to close this.
