Re: [zelig] Error: "no such index at level 1"

Hi - Zelig 4.1-2 has just been put on CRAN (as of... a few minutes ago). This may solve your issue. If not, I will release a nightly fix for it. To download the patch immediately, enter the following into the R-console: install.packages("Zelig", type = "source", repos = "http://iqss.github.com/") To download directly from CRAN (available later tonight, as it goes through the mirrors): install.packages("Zelig") On Jan 24, 2013, at 12:43 PM, Olivia Lau wrote: Which version of Zelig are you using? If version 4+, could you roll back to 3.x and see if you have the same error?
