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).
