silly, extracting the value of "C" from the results of somers2
...t; 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?
Thank you useRs,
very gratefull

scaling y-axis to relative frequency in multiple histogram (multhist)
...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

how to apply the function cut( ) to many columns in a data.frame?
..., sd=25)
df <- data.frame(var,x1,x2,x3)
df
# classifying the values of the vector df$x1 into bins of width 5
df$x1 <- cut(df$x1, br=5*(0:40), labels=5*(1:40))
df$x1
# trying it a subset of the data.frame
df[,3:4] <- cut(df[,3:4], br=5*(0:40), labels=5*(1:40))
df[,3:4]

Loading Excel file into Limma
Dear mailing group,
