i would like to plot a subset of variables with the highest variable
importance measures (say the top 20) instead of plotting all of the
variables included in the analysis (~75). i tried arguments that work to
restrict the number of variables displayed in the plot in randomForest as
follows:
when i try to validate my logistic regression model:
fit-glm(y~x,binomial,data=dataname,x=TRUE,y=TRUE)
validate(fit,method=boot,B=150,...)
i get the following error message:
Error in UseMethod(validate) : no applicable method for validate
any insight would be appreciated. many thanks!

I am trying to plot survival curves using the following code as an example:
rs1799964.coxph-(coxph(Surv(sassurvmonths,status)~age+stage+rs1799964_TNFA,method=efron))
plot(rs1799964.coxph,lyt=c(1,3),xlab=Survival in Months,ylab=Proportion
Surviving)
I am gettingthe following error message:
