[R] correction for density plot question

sorry! I ment to plot the probability vs. the values of course. not the probability vs. the density... cheers,gregor __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-proj

[R] density plot & probabilities

hello ! I have question concerning *kernel density plots*: how to plot of a vector, when that vector is very short (5-10 values)? I tried: > plot(density(x)) or > hist(x,probability=T,border="white") > lines(density(x)) for small length of vectors, the ylab is not 0from 0 to 3. thats confu

[R] PCA loadings differ vastly!

hi, I have two questions: #first (SPSS vs. R): I just compared the output of different PCA routines in R (pca, prcomp, princomp) with results from SPSS. the loadings of the variables differ vastly! in SPSS the variables load constantly higher than in R. I made sure that both progr. use the cor

[R] ANOVA between & within variance

hi, is there an option to calculate the 'within' & 'between' group variances for a simple ANOVA (aov) model (2 groups, 1 trait, normally distr.) ? or do I have to calculate them from the Sum Sq ? thanks for your time and greetings, gregor -- Gregor Rolshau
