R: How can I install a specific version of install_github ()?

Question

Devtools is a great package. If the current version of the package gives some errors, users may prefer to install a specific version (for example, version 1.0.1).

What code can be used to achieve this?

For example, for this package https://github.com/OHDSI/OhdsiRTools/tree/v1.0.1

A command like install_github ("OHDSI / OhdsiRTools", ref = 'v1.0.1')

Invalid code. It only works for branches (e.g. master or devA). But the devtool package has functions for linking to releases.

Ideally, I would like to refer to releases by their tag (but a solution with a commit identifier will work too).

ADDITIONAL BONUS: Which code can install the "latest" version. (but consider this a bonus question. The question is whether the main one)

Answer 1

You need to add tags for releases directly to the repository argument name. So it username/repo@releasetagwill work. Use only the option ref = "devA"when you need to access a specific git repository branch.

For your example, regarding OhdsiRTools v1.0.1 , we have

we have:

devtools::install_github("OHDSI/OhdsiRTools@v1.0.1")

Edit

After visiting the source, devtoolsI was curious that you can request the last source using

username/repo@*release

Therefore, you can use:

devtools::install_github("OHDSI/OhdsiRTools@*release")

Edit end
