[R] R for Windows GUI closes when I try to read.spss

[Roderick Harrison]

** High Priority **

I have been trying to read an SPSS file into R using 

read.spss ("C:/Documents and Settings/Roderick Harrison/My
Documents/RWORK/ihisdat.sav", use.value.labels = TRUE, to.data.frame =
FALSE,  max.value.labels = 500, trim.factor.names = FALSE, trim_values =
TRUE, reencode = NA, use.missings = to.data.frame)

Each time (at least 5 or 6 by now) I get the following Microsoft error
message and the R-Console crashes.

R for Windows GUI front-end has encountered a problem and needs to
close.  We are sorry for the inconvenience.

I would greatly appreciate help with this as we need to use R to
estimate confidence intervals for NHIS data, and our deliverable is due
this week.  

Thanks in advance.
