I tried to install it from binary on R-devel R Under development (unstable) (2013-02-13 r61942) -- "Unsuffered Consequences" Copyright (C) 2013 The R Foundation for Statistical Computing ISBN 3-900051-07-0 Platform: i386-w64-mingw32/i386 (32-bit) It does not load with error library(ReadImages) Error: package 'ReadImages' was built before R 3.0.0: please re-install it So I presume I could try to build it from sources, which can be beyound my expertise, if there was some tweak issues. This is probably the last resort for me.
