Re: [R] make check in 1.8.1.

[Don MacQueen]

Whatever it is, it's apparently a bit on the subtle side. Perhaps a 
previous test loads the data, and for some reason that previous test 
doesn't run for you. I couldn't find one that did, though.

From my 'make check':

running code in '../../source/tests/reg-tests-3.R' ... OK
comparing 'reg-tests-3.Rout' to 
'../../source/tests/reg-tests-3.Rout.save' ... OK

And my reg-tests-3.R does not have the data() statement:

if(require(MASS)) {
    fit <- lm(formula = 1000/MPG.city ~ Weight + Cylinders + Type + 
EngineSize + DriveTrain, data = Cars93)
    print(lm.influence(fit))
    ## row 57 should have hat = 1 and 
resid=0.                                                                             
    summary(influence.measures(fit))
}

I just (finally!!!) got R version 1.8.1 to configure and build under

Anyhow, when I ran ``make check'' I got an error right toward the
end.  Looking in the directory ``tests'' I found that the error was
associated with the file reg-tests-3.R, and the complaint was that it
couldn't find the object Cars93 from the MASS package.
So I edited reg-tests-3.R and stuck in the line ``data(Cars93)'':

===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===
## lm.influence where hat[1] == 1
if(require(MASS)) {
#
     data(Cars93)  # <------------------------- INSERTED LINE
#
    fit <- lm(formula = 1000/MPG.city ~ Weight + Cylinders + Type + 
EngineSize + DriveTrain, data = Cars93)
    print(lm.influence(fit))
    ## row 57 should have hat = 1 and resid=0.
    summary(influence.measures(fit))
}
## only last two cols in row 57 should be influential
===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===

Then I re-ran make check, and everything seemed to go OK.

I had a brief scan of the r-help mailing list archives just now and
could find no allusions to this problem.
Has anyone else encountered the problem?  ***Should*** that line
``data(Cars93)'' be in the code?  If not, what is going on?  If so,
why hasn't anyone else been bitten?  (Like, I mean, why me?) :-)
				cheers,
