R help - Jan 2014 - Regression on presence/absence matrix

Dear all: 

I want to predict a presence/absence vector using a presence/absence matrix of
events. What library can do this in R?

Many thanks

The library of packages that installs with R includes the stats
package, in the stats package is the glm function for fitting
generalized linear models.  Using glm with a binomial family will fit
a logistic regression which can be used as you describe.

If you really feel the need to use an additional package then lrm in
the rms package is another option (and I am sure there are others as
well).

I will answer your question only if you learn to say ***package*** and 
NOT "library".  The library() function loads ***packages*** from a 
library (= collection of packages).  Correct terminology is essential to 
effective communication.
