Hello,
I have two questions:
1. I am looking for some guidance on installing the EI version for R. I have been able to install several related packages (i.e., the standalone version of EzI, and eiPack from the CRAN site), but so far I have had no luck with EI for R. I attempted both of the installation methods suggested on the EI website. Unfortunately, our firewalls block installation EI from within R. The direct download method doesn't work, either (I get messages such as "Error in library(ei) : 'ei' is not a valid installed package." Can you suggest an alternative installation method? Do you plan to post EI on the CRAN site?
2. What are the main differences in functionality between EI for R, eiPack, and the EI-related functions in Zelig?
Thanks,
Connie
