I have just installed R2.9.0 on my Windows XP system. I have followed the same installation procedure I have been using for over a year. That is installation from the "exe" file. "kernel" belongs to package "stats"which is (I think) installed by default. I loaded it but did not use the command: > library(stats) Now I did and it works fine for me too. I am sorry. I though such a command is only necessary when a package is installed. Thank youi. Maura

Have you loaded some specific package? Which R versioj is this? Your OS? Self-compiled R or some pre-compiled binary?
