Dear R helpers,
I have been using the loadings function from the multiv library and I
get the typical output (see below). When I try to export these results
to a file using a write.table() I get the following error message
"Error in as.data.frame.default(x[[i]], optional = TRUE) : can't coerce
loadings into a data.frame" Any idea why write.table is doing that and
any possible solutions??
thanks
hector

?write.table says
`write.table' prints its required argument `x' (after converting
it to a data frame if it is not one already) to `file'.
There is no in-built way to convert a `loadings' object to a data frame,
but as it is a matrix (see ?princomp), unclass(loadings(foo)) will work.

^unclass( ^) Note that you do get just the loadings, not the full output from print.loadings.
