Hi,

after upgrading my R install from 2.5 -> 2.6.1 and performing multiple iterations of update.packages(), I am getting an odd error when trying to plot a calibration curve from the val.prob() function in package Design.

when running this function (which used to work) I get the following error message:

Error in .C("lowess", x = as.double(xy$x[o]), as.double(xy$y[o]), n, as.double(f), :
  C symbol name "lowess" not in DLL for package "base"

Here is my relevent session info:

Any ideas?
