R devel - Mar 2003 - small error in regression tests

I just r-sync'ed the r-devel version of R-1.7.0 (2003-03-11), compiled it
under RH-8.0 and ran make check.  The reg-tests-2 fails at the very end
with the message stating that "object cement was not found".  It looks
like
this piece of the regression test is new to version 1.7.  The the piece of
code generating the error is:

if(require(MASS)) {
    teststep <- function(formula, data)
    {
        d2 <- data
        fit <- lm(formula, data=d2)
        step(fit)
    }
    teststep(formula(y ~ .), cement)
    detach("package:MASS")
}

It seems that it requires
        data(cement)
statement before the call to teststep.

Thank you for the report.

[but this does *not* belong to R-help: it's about the "unstable"
 R development version!]

Not quite.  It requires the corresponding version of the VR
bundle (with its main part MASS).

After unpacking the R-devel sources,
you need to get the **corresponding**  recommended packages by
typing
	tools/rsync-recommended

before you configure and make !
