Dear R users: Suppose I have two different response variables y1, y2 that I regress separately on the different explanatory variables, x1 and x2 respectively. I need to compare points on two regression lines. These are the x and y values for each lines. x1<-c(0.5,1.0,2.5,5.0,10.0) y1<-c(204,407,1195,27404313) x2<-c(2.5,5.0,10.0,25.0) y2<-c(440,713,1520,2634) Suppose we need to

Dear ALL: I have two quick questions about how to perform some steps in R. Could you please see the attached MS file if the data not clean enough in this email. Thank you so much for all your helps. Abou Here it is: ========================= Consider the following matrix: data<-matrix(c(2,2,12,2,1,10,10,4,10,1,1,2,2,1,2,10,3,1,1,1,3,5,17,23,9,9,3,3,15,5,

Dear All: Urgent help is needed. I have a data set in matrix format of three columns: X, Y and index of four groups (1,2,3,4). What I need to do is the following; 1- How I can subtract the sample mean of each group indexed 1,2,3,4 from the corresponding data values of this group and create new columns say X-sample mean and Y-sample mean? I tried to use the "tapply" but

I have empirical Bayes estimates for slopes and intercepts for a number of subjects and I would like to plot the slopes and intercepts with confidence ellipses. These ellipses would be based on the confidence intervals for the slope and intercepts (forming the major and minor axis of each ellipse), and the correlation in the slope and intercepts. The ellipse function in the car library

Hello, R-Help - I am trying to plot the results of an ordination from package vegan. The tricky part for me right now is getting the colors of the ellipses denoting the 95% confidence intervals of the group centroids to match the colors of the points for those same groups. >From and earlier post, I saw the code to make a plot of the ordination using different colors for my different groups.

Many thanks to Andy Liaw for quickly reminding me of "ellipse" package in CRAN. It is apparently what I wanted. Not sure whether it will work in S-PLUS or not. But I will give it a try. Thank you.

Hello, I'm developing an ordination using metaMDS (package vegan). The analysis identifies 3 distinct groups that I'd like to define by either adding circles or ellipses to help identify the groups. The data set is a spatial temporal data base depicting change in each of 4 areas over 3 time periods. I can add lines that would link each of the time - x - area trajectories, but

hi, i am using this script on our webserver to plot data / draw ellipses for a flex movie... would like to add the areas of the ellipses to another legend just like the means for the distance. the data looks like: x (dispersion), y (distance), Club (name of the club for grouping) thanks, sam ## usage: Rscript nikeScatter.R infile outfile level1 level2 minX maxX minY maxY ## load

Hello R users! I began with R and I must say that it is really nice. I have data with a lot of variables and have a problem to extract the pattern from correlation matrix. So I tried with plotcorr and it went fine. While I was reading the help page of this function, I found that ellipse display can be even better with use of different colors (the code is bellow). However I have a problem to

Hello again, First I want to thank all the people who answered my question about line width in graphs. I promise I will learn the 'par' help page by heart for the end of the month ! I now want to trace some ellipses to emphasize groups of data. I found how to trace circles with 'symbols()', but no ellipse. I'm planning on writing my own function based on

Hi, I have read your post about plotting multiple CI ellipses and I would like too, but I don?t know how. I would like to plot an ellipse for each group and I have slope and intercepts, but I don?t know what to put in the arguments shape and radius. CAn you help me please?

Hello, has anybody written a function to plot density ellipses (95%, 99% or anything) in a scatterplot? I found nothing in any package, nor in the list archives. There does seem to be a contributed package "ellipse" for S-Plus (on S-Archive), but it does a lot more than what I would need. Still, if anybody ported it to R, I'd be grateful for a link. I'm a bit afraid to try the

Hi, I'm using the R library(car) to draw confidence/prediction ellipses in a scatterplot. >From what i understood the ellipse() function return an ellipse based parameters: shape, center, radius . If i read dataEllipse() function i can see how these parameters are calculated for a confidence ellipse. ibrary(car) a=c(12,12,4,5,63,63,23) b=c(13,15,7,10,73,83,43) v <-

Dear list members, This might be a silly question but I just can't figure it out. I am using the "ellipse" package on covariance matrices. I would simply like to plot my ellipses WITH its two axis ploted as well. These axis represents the 2 eigen vectors of my matrix and it is important that I can graphically show them. Is there an easy way to do so? Many thanks, Antoine -- View

Dear S-PLUS/R users: Do you know any default function or a user contributed function that can draw an ellipse with given axes and origin? Thanks for any help.

A rather strange situation here and I've not found the source of the problem. The point is to print a ternary plot matrix of compositional data with ellipses enclosing 95% of the variance in each plot. The ellipses display on the monitor, dev = x11cairo (see attached winters-x11cairo.pdf), but not when sent directly to a file, dev = pdf (see attached winters-pdf.pdf). Here's
