R help - Apr 2005 - how to print error message in batch mode

Dear list,
I am using R in batch mode:

$ R -q --no-save < prova > output

the input file "prova" has these commands:

data(USArrests)
x<-USArrests
hist(x)

of course, the command hist(x) produces an error. The error message is: 
Error in hist.default(x) : `x' must be numeric.
Is there the possibility to save this error massage in the "output"
file?
Thanks in advance,
Angelo

You could do something like
  $ R -q --no-save < prova > prova.out 2> prova.err
