R Question

How do you read the helpfile/manual for an older version of a package function without installing the package?

From Installing older version of R package, I am able to download the source for

dplyr
version
0.4.3
. I would like to see the helpfile for the function
collect
from this release, as I believe its behaviour has changed in
0.5
.

How do I see the old manual/help file without installing the old package?

Answer

I'm surprised that no one mentioned this:

compute in dplyr 0.4.3

compute in dplyr 0.5.0

  1. find package in RDocumentation
  2. select package and version
  3. search function for documentation. Though collect is actually documented in compute. Maybe you would need a google search to find about this if you didn't know it beforehand.
