[R] Dear professor

Dear professor：

When I used s-plus to run a Buckley-James Multiple Regression Model, the
program said Object "na.delete" not found. I found that Design package
and Hmisc
package have been installed.

The database SDF1、program SCRIPT1 and a picture are in the attachment.

Would you please give me some valuable suggestions. Millions of thanks！！
