[R] Getting a complete vector of Theta estimates from Package LTM

[Jeff]

   I'm new to R and this list.
   I'm using the LTM package for the first time to estimate Rasch and grm
   models.
   I've  searched  the web and the list archives and have found an almost
   identical question to my current one, but I haven't found an answer. I'm
   going to repeat the question that someone else asked two years ago (March
   20, 2010) to see if anyone can provide an answer to this issue.
I am using package LTM to estimate a Rasch model:

irtestimates <- rasch(binRasch)

I want to get a single vector containing theta estimates for all
the  
rows (individuals) in my data matrix (hopefully in the same order
as  
my data matrix) such that the length of the theta vector = the
number  
of rows (participants) in my data matrix. I am using:

theta.est <- factor.scores(irtestimates,method="EAP")

The problem is that this does not return a vector of ALL the theta  
estimates, rather it gives me a summary of theta estimates
associated  
with each response pattern in my data along with the number of
times  
each response pattern occurs.  Any ideas on how to get the
complete  
vector of theta estimates? Thanks,
