Dear R users,

I am having trouble using the pca function in the multiv library.
I am trying to generate the values found in $rproj by using $evecs to
calculate linear combinations of my input data.  However, I have been not
been able to correctly calculate the $rproj values.

Using the following standard sample data, why does iris%*%pcprim$evecs[,]
not equal pcprim$rproj?


Many thanks,
