I think you might do well to consult a local statistical expert, as you appear to be out of your statistical depth here. Also, is this homework? If so, this is not a homework site (although posters sometimes get help anyway). Cheers, Bert Bert Gunter Genentech Nonclinical Biostatistics (650) 467

[R] Density plots for Chi-square and F-distribution on my data

Dear R-helpers, I want to compute the density plot (probability plot) of the Chi-square distribution. My 2 categorical variables are gender (male, female) and colors of the eyes (blue, green and brown). The sample size n = 100. The proportions are the following : male and blue eyes : 10% male

[R] Density plots

Dear group, I need help on two problems: 1. I am trying to plot density plots for each individual in 8 occasions. I can do this by subject wiht the code below: par(mfrow=c(4,2)) plot(density(all8scenarios$SIMCONC[all8scenarios$ID==1&all8scenarios$WSEQ==0])) plot(density(all8scenarios$SIMCONC[all

Re: [R] density plots using density.lf, data.frame and sort.int errors

My guess (unconfirmed) is that read.table() gives you a data frame but density.lf expects an atomic (= not a list = not a data frame) vector. Perhaps try density.lf(x[,1]) to just send the column -- the "drop" behavior should make sure this is an atomic vector. If that doesn't help, please do prov

[R] density plots using density.lf, data.frame and sort.int errors

Dear R help group: I am attempting to produce a density plot from a list of 2 values using the density.lf function and would appreciate any help, I hope I have done my homework reading the documentation but I still seem to be missing something basic. I have read the data as a table using read.
