search for: plotcorr

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 understand the process of generating the colors. The function cm.colors() with argument 11 produces sc...

In the plotcorr() function in the ellipse package, I want to position things differently depending on the size of the labels. I can use strwidth to find out the length of the labels, but only when there's a plot window open: it won't open one. Question: What function call says: make sure there's a...

Dear useRs, While exploring new R packages, I have found the Rattle. This screenshot http://rattle.togaware.com/rattle-correlation.png is very interesting (others are in http://rattle.togaware.com/rattle-screenshots.html ). Which function was used to produce this plot? Is such plotting of the correlation matrix a unique Rattle's feature? Unfortunately I have some weird problems with RGtk2

...entation now it's been ported to R (by Jesus Frias, thanks IOsu!) and I'm back as the maintainer. One of the things it did which we thought was kind of cute at the time was to use a few lines of Postscript code to define a font, where the glyphs were ellipses of various shapes, used in the plotcorr function to display big correlation matrices. This isn't needed, strictly speaking: the current port draws the ellipses using polygon() and lines(). But drawing them with calls to text() was quite a bit faster, resulted in much smaller output files, and just generally seemed like a good ide...

good morning to the R-help list!, I would like to ask if there is an alternative to the S ploting parameter "cxy" in R. I am trying to port some S code to R that makes use of this "cxy" parameter to scale the graphics, and I don't find this parameter in help(par). thank you, IOsu ------------------------------------------------------------------------------- Jes?s
