This was working a few weeks ago, but perhaps the package has been updated since then.

model.1 <- lrm(response ~ p_value, data=c_abl_oncogene_1_RTK)

When I run the following command . . . .
prediction.1 <- predict(model.1, type=c("fitted"))
I get the following error message. . . .
Error in predictDesign(object, ..., type = "lp", se.fit = FALSE) :
  could not find function "Varcov"

It seems like a required function of "predict" may be missing in the Design package (although I doubt Professor Harrell would have overlooked this). Perhaps its my own stupidity with something. Any ideas what could be causing this?  I'm sorry I didn't post a reproducable example, but it a lot of code.

Any help would be appreciated.

Best regards,

Patrick
