It is exactly as Brian Ripley said: If I just start R and execute

set.seed(1)

hist(replicate(100, mean(rexp(10))))

everything works well. However, if I run "make check" the error occurs.
Now I have tried something inbetween: I started R and source()d the file that
caused the error. The error occured again:
R> sink("base-Ex.Rout")

R> source("tests/Examples/base-Ex.R",echo=TRUE)

Then I typed

R> traceback()

6: stop("invalid number of 'breaks'") 5: hist.default(replicate(100, mean(rexp(10)))) 4: hist(replicate(100, mean(rexp(10)))) 3: eval.with.vis(expr, envir, enclos) 2: eval.with.vis(ei, envir) 1: source("tests/Examples/base-Ex.R")

After sourcing this file it is impossible to use hist() because always the
same error message occurs:

R> hist(rnorm(55))

Fehler in hist.default(rnorm(55)) : invalid number of 'breaks'
R> traceback()

3: stop("invalid number of 'breaks'") 2: hist.default(rnorm(55)) 1: hist(rnorm(55))

R> hist(c(1,2,2))

Fehler in hist.default(c(1, 2, 2)) : invalid number of 'breaks' R> traceback()

3: stop("invalid number of 'breaks'") 2: hist.default(c(1, 2, 2)) 1: hist(c(1, 2, 2))

This seems to be independent from argument x (the values).

Cheers,

Arne
