I'm fairly sure I understand all that. I'm still missing something more
basic probably. Consider the follow workflow :
I look on CRAN at package boot. Its webpage states "Depends R (>=
2.14.0)". I'm a user running R and I know I use 2.14.1, so I think great I
can use it. I install it as follows.
version.string R version 2.14.1 (2011-12-22)
Content type 'application/zip' length 469615 bytes (458 Kb)
downloaded 458 Kb
package boot successfully unpacked and MD5 sums checked
Loading required package: boot
package boot was built under R version 2.14.2
Does this mean that CRAN maintainers expect me to run the latest version
of the major release I'm using (R 2.14.2 in this case), not the current
release of R (R 2.15.0 currently) as you wrote earlier? If that's the
case I never realised it before, but that seems very reasonable. When I
ran the above just now I expected it to say "package 'boot' was built
under R version 2.15.0". But it didn't, it said 2.14.2. So it seems to
be my misunderstanding.
