Hi, When I am using ldahist function I would like to specify different colors for each of the groups in the data I am using. Is it possible? If not does anybody know of another function to plot multiple histograms on one plot for different groups. Thanks ===== Thanks Fairouz Makhlouf

...15.14 16.54 I 543.4 646.56 J 54.4 654.5 K 646.5 64.54 L 645.4 614.46 M 646.54 634.46 I want to make a histogram each for A1 and A2, with density curves, on the same plot so that I can see how they overlap. Please let me know some simple code for this. I looked at ldahist but it was complicated. Anything simpler? Thanks a lot, -DS. [[alternative HTML version deleted]]

Hello, Does anyone knows how to do the plots from discriminant analysis (lda and qda)? Is there any computed function to do the stepwise procedure? thank you in advance Marta

Hi all, I am trying to plot the results of a discriminant analysis done with lda(MASS) but my groups appear in two different plots (in the same graphics device) and I want to combine them in one plot. My code looks like: BirdTrain.lda <- lda(Bdisperser~., data=BirdTrain.mx) predict(BirdTrain.lda) plot(BirdTrain.lda) I have two types of Bdisperser, so I only get one linear discriminant

...the one-dimensional predictions (histograms) from lda() (MASS) discriminant function objects? While the helpfile suggests that a histogram is returned by default, the presumably proportion-like values for each group seem to add up to more than 1, and I'm not sure how to interpret the code from ldahist(), which, I believe, defines the heights of each bin as est1/(diff(breaks) * length(data[g == grp])) where est1 is (as far as I can tell) the frequency within the bin, and the denominator is apparently the bin width multiplied by the total sample size for that panel. It seems to be that a far m...
