Hi Zelig,

I’m having trouble loading the Zelig package to my machine.
My goal is to use the ei.RxC model, but I can’t get access Zelig to begin with.

I installed the Zelig 4.2-1 version, but when I call
library(Zelig), I get an error:

Error : .onAttach failed in attachNamespace() for 'Zelig',
details:

call: NULL

error: '.readRDS' is
defunct.

Use 'readRDS' instead.

See help("Defunct")

Error: package or namespace load failed for ‘Zelig’

I also rolled back Zelig to version 3.5 on the hopes
that it would work, but no change.

I have been following the installation guide (http://zeligdev.github.io/files/zelig.pdf), among many other resources, and I am using R version 3.0.2.

I have also noticed others have had this problem in the past (http://comments.gmane.org/gmane.comp.lang.r.zelig/783) but downloading from the CRAN Network as opposed to manually with an install.packages() command made no difference in my case.

Please any advice on what I am doing wrong here?

Thanks,

Jennifer Boylan
