Install roxygen 6.0.1 for Windows

InstallRoxygen601.R

# Currently roxygen 6.1.0 doesn't read the collate field correctly, so once you use @include anywhere
# in your package, you run into problems. The error you get, is a 'Permission denied' error. If that
# occurs, best thing to do for now is to install the previous version of roxygen until
# the problem is solved.
#
# I've made a binary build for Windows available. You can download it manually from following link:
# https://jorismeys.stackstorage.com/s/co8cKzyRemVHZef
# Alas the filesharing I use doesn't allow automatic downloading through download.file(), so you
# have to go to that link and click on Download to get the actual zip file.
#
# Save it in a location, eg C:/Temp.
# Then run the following:

install.packages("C:/Temp/roxygen_6.0.1.zip", repos = NULL, type = "win.binary")

# Replace C:/Temp/ by the folder where you stored the zip file.
