Thanks Jeff. I am probably not explaining myself very well but my
question under what circumstances would
summary(file(remote_file, "rb"))$`can read`
be different from:
file.access(remote_file, 4)
If my permissions were different across remote and local should that
not be reflected in both of these functions?
