Let's say I want to use in my R package a development version of a dependency as it stands on a certain GitHub branch, but the additional complication is that it resides in a subdirectory.
For example, if I wanted to rely on the glmmTMB package from this branch, I can download it using remotes like so:
remotes::install_github("glmmTMB/glmmTMB@ci_tweaks", subdir = "glmmTMB")
If this package were not based in a subdirectory, I could have included the following in the DESCRIPTION file:
Remotes: glmmTMB/glmmTMB@ci_tweaks
But I don't know how to specify a subdirectory here to get the package.
You should know that remotes creates all needed DESCRIPTION file fields for you. So I run the remotes::install_github("glmmTMB/glmmTMB@ci_tweaks", subdir = "glmmTMB") and then packageDescription("glmmTMB"). Check out how many Remote and Github connected fileds are added. There is e.g. RemoteSubdir: glmmTMB too.

Description: Fit linear and generalized linear mixed models with various extensions,
including zero-inflation. The models are fitted using maximum likelihood
estimation via 'TMB' (Template Model Builder). Random effects are assumed to be
Gaussian on the scale of the linear predictor and are integrated out using the
Laplace approximation. Gradients are calculated using automatic differentiation.
