Unable to install

User can't install on Windows R 3.5.2.

Error: package or namespace load failed for ‘spider’:
.onLoad failed in loadNamespace() for 'sf', details:
call: get(genname, envir = envir)
error: object 'group_map' not found

See email from Clive.

• I have the same error message when installing on macOS Mojave with R 3.5.0 or 3.5.2.

> library("spider", lib.loc="/Library/Frameworks/R.framework/Versions/3.5/Resources/library")

Sorry for the delay @gbdias
I think this is an issue with installing the "ape" and "pegas" dependencies.
Can you try installing these separately, and see what happens?
