Reinstalling binary dependencies — reinstalling • glmmTMB

The glmmTMB package depends on several upstream packages, which it uses in a way that depends heavily on their internal (binary) structure. Sometimes, therefore, installing an update to one of these packages will require that you re-install a binary-compatible version of glmmTMB, i.e. a version that has been compiled with the updated version of the upstream package.

If you have development tools (compilers etc.) installed, you should be able to re-install a binary-compatible version of the package by running install.packages("glmmTMB", type="source"). If you want to install the development version of glmmTMB instead, you can use remotes::install_github("glmmTMB/glmmTMB/glmmTMB"). (On Windows, you can install development tools following the instructions at https://cran.r-project.org/bin/windows/Rtools/; on MacOS, see https://mac.r-project.org/tools/.)
If you do not have development tools and can't/don't want to install them (and so can't install packages with compiled code from source), you have two choices:
- revert the upstream package(s) to their previous binary version. For example, using the checkpoint package:
```
## load (installing if necessary) the checkpoint package
while (!require("checkpoint")) install.packages("checkpoint")
## retrieve build date of installed version of glmmTMB
bd <- as.character(asDateBuilt(
      packageDescription("glmmTMB",fields="Built")))
oldrepo <- getOption("repos")
use_mran_snapshot(bd) ## was setSnapshot() pre-checkpoint v1.0.0
install.packages("TMB")
options(repos=oldrepo) ## restore original repo
```
  A similar recipe (substituting Matrix for TMB and TMB for glmmTMB) can be used if you get warnings about an incompatibility between TMB and Matrix.
- hope that the glmmTMB maintainers have posted a binary version of the package that works with your system; try installing it via install.packages("glmmTMB",repos="https://glmmTMB.github.io/glmmTMB/repos",type="binary") If this doesn't work, please file an issue (with full details about your operating system and R version) asking the maintainers to build and post an appropriate binary version of the package.
