[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))
}
