R help - Nov 2005 - survdiff for Left-truncated and right-censored data

dear all,

I would like to know whether survdiff and survReg function in the 
survival package work for left-truncated and right-censored data.

If not, what other functions can i use to make comparison between two 
survival curves with LTRC data.

thanks for any help given

The survdiff and survfit functions do, as does coxph.  There is no survReg 
in the survival package, but there is survreg, and it does not handle left 
truncation.
