reg-tests-1a fails with r70391

Hi,

This may be a `transitional' bug but I am reporting a make check
fail with R-devel r70391 in reg-tests-1a.Rout. The tail of
reg-tests-1a.Rout.fail is

Error: length(s$sdev) == ncol(s$rotation) is not TRUE
Execution halted

Looking at stats:::prcomp.default(), it appears that s$v is
truncated but not s$d (unlike in the code before r70391) for the
reduced rank case.

h.

Exactly.  I had this in the list of changes to be committed in
r70391, but not on the computer I did commit.

The 'transitional' period (above) has terminated 2 minutes ago.
Thank you, Hiroyuki for the reminder.
