This was working a few weeks ago, but perhaps the package has been

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.
No, Prof Harrell did not overlook this. Instead he rewrote the whole
package which is now "rms". The missing Varcov function was made
available in an earlier posting to r-help just a couple of days ago.
