Hi,
I am not sure if I am going to have to wait to submit extra revisions.
However, I am unfortunately having the same issue (even though I tested using
the temporary directory instead of the current working directory, in COHCAP
(v.1.33.4).
I also tested changing the file path to the temporary in v.1.33.6, but that
also didn't fix the problem (and I might change that back).
I am also still not able to reproduce this error message on my end.
For example, this is what the output of the build command looks like:
C:\Users\Charles\Documents>"C:\Program Files\R\R-4.0.0\bin\R.exe" CMD build
COHCAP
* checking for file 'COHCAP/DESCRIPTION' ... OK
* preparing 'COHCAP':
* checking DESCRIPTION meta-information ... OK
* cleaning src
* installing the package to build vignettes
* creating vignettes ... OK
* cleaning src
* checking for LF line-endings in source and make files and shell scripts
* checking for empty or unneeded directories
* building 'COHCAP_1.33.6.tar.gz'
And, I can also install COHCAP successfully using devtools (in R-4.0.0),
although it does have some warnings:
> library("devtools")
Loading required package: usethis
> devtools::install_github("cwarden45/COHCAP")
Skipping install of 'COHCAP' from a github remote, the SHA1 (09b017ba) has not

I am not sure if this last warning about the installation path has something to
do with using both the pre-release (previously) and release (currently)
versions of R-4.0.0.
Can you please help me know if you have any other troubleshooting suggestions
for the Window server used to test the Bioconductor packages?
Thank You,
Charles

FWIW here are 2 important reasons for writing temporary stuff to
tempdir() instead of the current working directory:
1. tempdir() is the only place that is guaranteed to be writable on every
system. Yes the user home is very likely to be writable too but there is
actually no guarantee and some systems have unconventional setups where it's
not.
2. Whatever you put in tempdir() will automatically be removed at the end of
the R session. Even though there are ways to achieve this with the temporary
stuff you write in the user home, it's not automatic and hard to get right.
Cheers,
H.
