Hello

Help with dataEllipse function
Hi Everyone,
I am working with the R function "dataEllipse". I plot the 95% confidence
ellipses for several different samples in the same plot and I color-code
the ellipse of each sample, but I do not know how to specify a different
line pattern for each ellipse. I can only modify the pattern for all
ellipses with the "lty" argument. Any help will be highly appreciated.

DataEllipse versus Ellipse Function in R
Hi:
Does Ellipse and dataellipse function in R produce the same ellipse? I
wanted to see how the radius for the Ellipse function in R calculated. Also
what is the var-covariance matrix, if any, assumed for the dataellipse
function? Heres an example of the code where I am generating Multivariate
normal data and creating ellipse using the 2 functions:

colored PCA biplot
Hi-
I'm trying to make my PCA (princomp) colored. In my csv excel sheet, I have
the first column numbered according to the groupings I want to assign to the
PCA. I've played around with trying to set this first column as the color
vector, but haven't had any luck.
Any suggestions? Thanks,

confidence / prediction ellipse
Hi,
I'm using the R library(car) to draw confidence/prediction ellipses in a
scatterplot.

If i read dataEllipse() function i can see how these parameters are
calculated for a confidence ellipse.
