Hi there,

I hope this question is not as stupid as the one before ...
I tried to shorten my histogram (because the distribution is quite skewed and I 
simply don't want to see the long tail but still use the histogram plot). How 
can I do something like this? (The example does not work but I don't know why...)

data <- rnorm(100) # as example, of course this is not skewed...

h <- hist(data, plot=FALSE)
mh <- 5
hh <- list(h$breaks[0:(mh+1)], 
h$counts[0:mh],h$intensities[0:mh],h$density[0:mh],h$mids[0:mh],h$xname,h$equidist)
names(hh) <- names(h)
plot(hh)

Antje,

Have a look at ?hist. It seems like you want this:

data  <- rnorm(100)
hist(data, xlim = c(0,6))

HTH,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

Hmm not sure if this is what you want, but maybe subset the data:

hist(data[data > -1])

m.

Thanks a lot, that's exactly what I need :-) (I did not consider the class...)
Putting an xlim could also be an solution but I think this is much more clean :-)

Ciao,
