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?...
