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 -- ahimsa campos-arceiz www.camposarceiz.com [[alternative HTML version deleted]]

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

I have tried: > z$C NULL > z[,C] Error in z[,C]: incorrect number of dimensions and some other silly
