R devel - Feb 2005 - barplot: space makes beside=F (PR#7668)

Hi,
I had a R version 1.5.1 and I used a 'barplot' with 'beside=T'
and 'space' has
been vector of 8 numbers 'space=c(1,0.5,rep(c(0.5,-0.5),3))'. Then I
upgraded to
the R 2.0.1 and my graphs are broken. If I use any vector of more than 2
elements for 'space' then the graph is drawn as 'beside=F' even
if I specify
'beside=T'. 

In the previous version my graph was a graph of groups of eight bars separated
by a big spaces. Every group consisted of 4 pairs of bars separated by a small
space. It's impossible now.

This is not a bug. See ?barplot which tells us:

    space: [...] If height is a matrix and beside is TRUE,
           space may be specified by two numbers, where the
           first is the space between bars in the same group,
           and the second the space between the groups. [...]

and it works as described:

    barplot(matrix(1:10, 2), beside = TRUE, space = c(1, 7))

Hi Ondrej,

can you give a very small *REPRODUCIBLE* example
of R code that worked in R 1.5.1 and doesn't work the same in R
2.0.1.

I know that we made some changes for barplot() on purpose,
documented it, announced it in NEWS, etc, etc.
So I'm sure it's not a bug.  

{ I'm also sure that your
    ``It's impossible now ''
  must be wrong. R is a full-fledged programming language, and in
  principle everything is possible :-)
}
