barplot

Sorry for incomplete posting:
I am using R 0.90.0 for Win95/NT
Hence, the correct workaround is:

barplot(c(.1,.5,1.0),ylim=c(-0.01,1.01))

as proposed by Prof. Ripley instead of:

barplot(c(.1,.5,1.0),ylim=range(-0.01:1.01))

which works for lower versions (I suppose).
I have caused all the unclearness by non-citing the R version, so 
sorry again and thanks for the solution!

Actually, it's a problem in any version of R since way back:

range(-0.01:1.01)

[1] -0.01  0.99

(a:b gives sequences in steps of 1, starting from a and stopping
before b is exceeded).

Perhaps this could be mentioned in the help to the range(), since the current 
text "range returns a vector containing the minimum and maximum of all the 
given arguments" seems to be a bit confusing to me.

But that's what it does:

-0.01:1.01

[1] -0.01  0.99

as Peter pointed out, it's not a range() problem. The source of your
trouble is a misunderstanding about the meaning of the : operator.

Really. Sorry for all this posting.
