adding an ellipse to a PCA plot
Hi, I created a principal component plot using the first two principal components. I used the function princomp() to calculate the scores. now, I would like to superimpose an ellipse representing the center and the 95% confidence interval of a series of points in my plot (as to illustrate the grouping of my samples). I looked at the ellipse() function in the ellipse package but can't get it

Introduction to R. Any such documentation in Vietnamese?
Dear fellow users Are there any Vietnamese language resources for beginners of R? If so, I would be interested in hearing from people who have had experience with them and which are better (if there is more than one). I am involved with an aid project in Vietnam, and would like to move the scientists involved from using Excel for 'analysis' to R. Thanks .... Peter Alspach The

Discriminant plot
Hi Alejo, According to my knowledge the two plots are different because in the first one a point belongs to a group depending on its group in the data whereas in the second plot a point belongs to the group predicted by the linear discriminant analysis. I hope somebody will correct me if I am wrong. Alain Alejo C.S. wrote: > Hi Alain, this is the code: > > > library(MASS) >

Constraining linear regression model
Hi All, I have two questions: I am computing a linear regression model with 0 as Intercept. Well, I would like the sum of my predicted values be equal to a constant and therefore analyze if my coefficients are significatively different using or not this constraint. Does anyone know how I can constrain my model in a such way? Here is the code: data<-read.table ("input.txt",

Size of plots in pdf files#can it be smaller?
Hi all, I have to produce arrangements of 25 simple plots of the type plot(x,y,pch=".") where there are typically on the order of 20000 points. So, overall, I have about 500000 points. When I use the pdf device, I get file sizes (on a Windows machine) of about 10 MB. When I then zip the files, I'm down to about 0.5MB, so the original pdf files were created with a lot of
