[R] chron and R 2.8

[Gabor Grothendieck]

To run the old version of chron that you have under 2.7.2
into 2.8.0, on 2.7.2 issue the command (note initial dot):

.libPaths()

Suppose you find that the library that contains chron in
2.7.2 is "/a/b".

Then on 2.8.0 ensure that you don't have chron on the search path

search()

and if you do detach it:

detach("package:chron")
search() # should no longer be there

Then run this where "..." is the library that the old version of chron
is in under 2.7.2.

library(chron, lib = "...")

To run the new version of chron detach the old version and just use:

library(chron)
