[R] Error: could not find function "invlogit" and "bayesglm"

[S'dumo Masango]

I have installed the arm package and its dependents (e.g MATRIX, etc), but
cannot use the functions "invlogit" and "bayesglm" because it gives me the
error message "Error: could not find function "invlogit" or Error: could not
find function "invlogit". What could be the problem.



Regards

Hi Carrington,

You also need the boot package (see
http://stat.ethz.ch/R-manual/R-patched/library/boot/html/inv.logit.html )
As for the other function, please load the arm package, e.g.,

require(arm)
require(boot)

and then you will be able to use the functions mentioned below.

HTH,
Jorge.-
