I was loading AIMS package and got a warning:

package ‘AIMS’ was built under R version 3.2.0

I thought R-3.1.2 ("Pumpkin Helmet") was the latest release so I checked on CRAN and couldn't see anything about a R-3.2.0.

Before calling it a typo, I googled the "problem" with different keywords and ended on this page from r-project site mentioning two R versions running, a R-release (R-3.1.2) and a "R-devel, to be R-3.2.0".
Googling "r_devel" confirmed what I was guessing, that this is the current development version.

I'm a bit surprised that packages can be built under the development version and I have a twofold question:
- How can a package already be built under a "to be released" R version and is it "safe"?
- Given that the development version is not released yet, how could I use the package with the R version it was built under? (Having a previous R version doesn't prevent me from using the package but I'm not sure I feel comfortable about the warning...)

Or maybe it was really just a typo?...

  • If you downloaded a binary, talk to BioC. If you downloaded source, just reinstall with R 3.1.2 (aka r-release) – Dirk Eddelbuettel Feb 04 '15 at 15:30
  • @DirkEddelbuettel, I installed it with command `source("http://bioconductor.org/biocLite.R");biocLite("AIMS")` (sorry, I'm not sure what to choose between your options...) – Cath Feb 04 '15 at 15:34
  • Do it again, but first start R-release (3.1.2) not R-devel. – Dirk Eddelbuettel Feb 04 '15 at 15:47
  • @DirkEddelbuettel, sorry if I wasn't clear, I'm not on the `R-devel` version (I wouldn't even know how to install it actually...) – Cath Feb 04 '15 at 15:51
  • I wouldn't bother too much if I were you. This is probably a typo, or maybe the binary was erroneously built under the development version. Anyway, I can't imagine anything can go wrong. If you want to get to the bottom of it, contact Bioconductor and/or package maintainer. – tonytonov Feb 04 '15 at 16:10
  • @tonytonov, thank you for your comment, I'll follow your advice and use the package as if there was no warning and contact the maintainer if I happen to notice something weird. Thanks again for your time (and thanks for fixing my own typo! ;-) ) – Cath Feb 05 '15 at 07:56
  • You are welcome! If you find something interesting, do not hesitate to post an answer for future reference. – tonytonov Feb 05 '15 at 08:39
