[R] new package error message

[Jason Liao]

My coauthor made a new R package GeneLogit (100% R code) which installs
ok on R 2.3 on Windows. But when I type

library(GeneLogit)

it gave the error message

Error in library(GeneLogit) : 'GeneLogit' is not a valid package --
installed < 2.0.0?

It runs on R 1.9.0 just fine. It seems that others have encountered
same problem but no solution is found by googling

How can I fix this problem? Many thanks.
