you need to learn the interface between R and Tcl for which there's a nice
(easy to find with Google) pdf document. If you really cannot find it,
I'll look it up for you.

Thanks, I tried using plotCI in the plotrix library.
This, however, gives me the below error.

Great, why didn't I think of that.

If you want to add lines as well as points, I think you will
have to use lines(x,y,type=b,lty = plot_linetypes[graph_idx]) in
addition to plotCI,

### -- The following line makes R hang with 100
Hi List,
Is it possible to tell R to use tcl/tk 8.5?
My R package seems to depend on libtcl8.4.so.
However, in Windows it seems to be possible to set
TCL_LIBRARY and MY_TCLTK.
Is there something similar possible in Linux?
I have installed:
$ rpm -q R
R-2.3.1-1.fc5
$ locate libtcl8
in case length(x) is not a multiple of length(arr).
(or the other way around if arr was longer than x)
I made a nice one for you:
g - function(x) rowSums( t(t(1/x)) %*% arr )
It is likely someone else can do it much nicer (shorter),
my R knowledge still has to be increased ...
JeeBee.

Slightly better:
h - function(x) rowSums( as.matrix(1/x) %*% arr )

Hi Alessandro,
The problem is that arr/x isn't quite doing what you
thought it was.
arr / x is something like
c(arr[1] / x[1], arr[2] / x[2], arr[1] / x[3
)
works, but it does not match J. TEST.
It does match J. Test correctly.
I have the feeling I'm not reading the documentation
good enough, but cannot seem to figure this out, sorry.
