scaling y-axis to relative frequency in multiple histogram (multhist)
...x)
mh <- list(rnorm(200, mean=200, sd=50), rnorm(200, mean=250, sd=50))
multhist(mh)
In this graph y-axis represents the frequency of observations.... but I
would like it to be scaled into relative frequencies,
does anybody know how to do this with multhist or similar function?
thanks a lot,
Ahimsa

silly, extracting the value of "C" from the results of somers2
...o do it. I have tried:
> z$C
NULL
> z[,C]
Error in z[,C]: incorrect number of dimensions
and some other silly things. If I do
>list(z)
[[1]]
C Dxy n Missing
0.88 0.76 500 0.00
Can somebody tell me how can I obtain just the value of c?

how to apply the function cut( ) to many columns in a data.frame?
...How can I make this work with data frames in which I want to apply the
function cut( ) to many columns in a data.frame?
I guess that I might have to use something like for ( ) (which I'm not
familiar with), but maybe you know a straight forward method to use with
data.frames.
Thanks a lot!

there are no Df to test the effect of the interaction S*t,
Can anybody give any insight on how should I test the effect of this
interaction?
Really thank you!

are different, but data structure is equivalent to mine.

Loading Excel file into Limma
Dear mailing group,
This is my first time here. Glad to have this resource!
I am currently trying to load an Excel file into R (limma package loaded)
using the source(*name of directory*) command, but it cannot open the file.
I renamed the file as .R and .RData, to no avail. The Excel data contains
one gene name per row and about 100 data points per gene (columns).
I am only used to

UNSOLITED E_MAILS: Integrate R data-analysis projects with Microsoft Office for free
Dear R Admins,
I received an unsolicited e-mail from BlueInference as an R
