Hi all,

I've ventured into the world of nonparametric survival and I would like to use the "maxtime" option for printing and plotting my aareg fit.

However, my fit does not have "test.var2" and this stops the print and plot when adding a maxtime.

My code is as follows:

Response<-Surv(Time,Event)
Model<-aareg(Response~Factor1*Factor2)
Model2<-aareg(Response~Factor1+Factor2)  #Just did this to see if the interaction term had anything to do with it

Model, print(Model), summary(Model), and plot(Model) seem to work fine, but as soon as I try summary/print/plot(Model, maxtime=400) it tells me that test.var2 is not found and when I look at  summary(Model), there is indeed a NULL under test.var2.

Anyone know why it doesn't include test.var2? Is this a compatibility problem? I'm using R version 2.13 (I know it's quite old, but updating is a pain when you don't have admin rights to your computer) and just updated the survival package (no warning messages).

Any input would be much appreciated.

Cheers,

Freya
