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

evaluation methods for logistic regression with proportion data
Dear list-members,
I have made a logistic regression analysis of the spatial distribution of
an ecological phenomenon (wildlife-caused crop damage). I divided the
region into 5x5 km grids, and in each grid I have performed a number of
questionnaires to asses the presence of crop damage in particular houses.
As a result, my dependent variable is not a simple presence/ absence data
but a

silly, extracting the value of "C" from the results of somers2
Sorry I have a very simple question:
I used somers2 function from Design package:
> z<- somers2(x,y, weights=w)
results are:
>z
C Dxy n Missing
0.88 0.76 500 0.00
Now I want to call only the value of C to be used in further analyses, but I
fail to do it. I have tried:
> z$C
NULL
> z[,C]
Error in z[,C]: incorrect number of dimensions
and some other silly
