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?

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

Thanks
