can't install from GitHub

[eosnas]

I tried to install AKaerial from GitHub. First time I tried, I got an error about 'not being able to update the package 'rlang'. I checked and there was no package 'rlang' in my directory, so I shut down R and tried again. Second try gave me this:

devtools::install_github("USFWS/AKaerial", ref = "master", build_vignettes = TRUE)
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘rlang’

Is this a namespace issue or is it on my side? Using R version 3.6.3 (2020-02-29) -- "Holding the Windsock"
Copyright (C) 2020 The R Foundation for Statistical Computing
Platform: x86_64-w64-mingw32/x64 (64-bit)

And RStudio Version 1.1.453

This seems to be caused by various dependencies of devtools and/or some interactions with RStudio and not AKaerial. See the link swirldev/swirl#709 and the links within. Uninstalling various packages, and installing AKaerial again worked after several tries.

Had the same issue. First, had to install Rtools (https://cran.r-project.org/bin/windows/Rtools/history.html). Then, when installing AKaerial, I would prompt through to update all necessary packages. But, the install seemed to stop/fail if there was a package that required R to restart. So, I manually updated those packages (i.e., Tools -> Install Packages; "rlang" among about 5 others). After that, install seemed to work and was able to reproduce the example Figures/Tables on my machine.

Current version of AKaerial cannot be istalled with newer versions of R

Should add troubleshooting guidance to readme.
