Hi, all
I am trying to write a R package. I was able to build and install the
package with no problem.
However, I got this error when I try to load the library by calling
library("btRRTest");
------------------error message in loading---------
> library("btRRTest")
Error in library("btRRTest") : 'btRRTest' is not a valid package --
installed < 2.0.0?

* overwriting 'INDEX' as '--force' was given

* checking for empty directories

-------install message-------
jasonportal:/home/jason/tmp2 # R CMD INSTALL btRRTest_0.0.1.tar.gz
* Installing *binary* package 'btRRTest' ...

Can anyone tell me what are the possible causes for this error? Where
should I start to look?
Thanks
