Dear List,



I?m doing my first baby steps towards developing own R Packages and

ran into

the following problem:

First baby step: Do not cross-post on several lists.

R CMD check mypackage works fine (no errors, no warnings)

R CMD build mypackage works fine (no errors, no warnings)

R CMD INSTALL ?library=?C:\R\R-2.11.1\library?
?something\mypackage\mypackage_1.0.tar.gz? works fine (no errors, no
warnings)



However, when I try loading the package in an R-Session (version

2.11.1) via

?library(mypackage)?, R complains about the package being build

before

version R-2.10.0 and tells me to rebuild it.

So the R that is in your PATH is  < 2.10.x
Change your PATH and add the R version your are actually working
with....

Could this possibly be due to the fact that I have multiple R

versions

installed (this also includes the most recent one, though)?



To provide you with some details:

-          Running Windows XP

-          All of my R versions are under ?C:\R? (versions 2.9.2,

2.10.1,

2.11.1).

-          I installed Rtools (version 2.1.2) to ?C:\Rtools? and

pointed it

to ?C:\R? (as this was the default) to interact with R (should this

maybe

have been ?C:\R\R-2.11.1??). I also installed everything else

necessary to

build packages (Inno Setup etc.).

-          My PATH is set up as explained in R-Admin manual. Also,

the only

R version stated there is ?C:\R\R-2.11.1\bin;?.

-          I updated the DESCRIPTION file and specified all .Rd files
correctly.



Any idea what I?m doing wrong?



Thanks a ton,

Janko
