R help - Oct 2008 - library MICE warning message

Hello.

I have run the command

imp<-mice(mydata,
im=c("","pmm","logreg","logreg"),m=5)
 for a variable with no missing data, a numeric one and two variables with
binary data.

I got the following message:

There were 37 warnings (use warnings() to see them)
> warnings()

Can somebody explain me what went wrong, and what do i have to do to correct it?

Thank you.

Not your fault: when you run the sample from mice{mice} with the current 
version of R, you get the same type of warnings. I have not checked the 
details, but I remember a similar case when we installed R version 2.7.0., 
which was harmless, but should be corrected. I will send a mail to Roel de 
Jong <dejongroel at gmail.com>.
