Hi Mariana.
You can download old versions of laser from the CRAN archive
(http://cran.r-project.org/src/contrib/Archive/laser/); however you will
have to build from source. This is easy if you have Xcode (for Mac OS)
or a gcc compiler installed. If you do not, and cannot figure out how to
install from source, then respond to the list & I'm sure someone will
help out & post a package binary for you.

Dear all:
I just performed a test of the gamma-statistic on my tree and I found that
diversification is not constant in time. So, I would like to perform the
function fitSPVAR, fitEXVAR and fitBOTHVAR using the laser package. But, I just
saw that the laser package was removed from the CRAN repository. Could anyone
tell me what other alternative package I could use to develop and test models
of decreasing speciation rate, increasing extinction rate or both? Does MEDUSA
do this sort of analyses?
Thank you for your help!
Mariana
