Dear list, When I use VennDiagram package, I got a error as follow: venn.plot <- draw.pairwise.venn( area1 = 3186, area2 = 325, cross.area = 5880); Error in draw.pairwise.venn(area1 = 3186, area2 = 325, cross.area = 588) : Impossible: cross section area too large. Does anyone have suggestion? Thank you.

Hi all, How to plot as the coordinate as in my attachment? I want to trim the coordinate and one of plot as the figure in attachment. Does any one have such example?

Dear R-developers, I am trying to experiment with projection pursuit (PP), and different indexes for the same, especially using the tourr package. However, I've noticed that a PP index in the said package is only a function of the projected data. Could I modify the function so that the index sees the projection bases instead (or in addition to the data) ? Alternatively, if some other package can be used this way, I would be grea...

Dear list, When I read some source code, I find lot of place used symbol <<- , e.g. lastTime <<- newTime; What is the meaning here? Also, I find some method with the name start with dot, e.g. .RowStandardizeCentered = function(x) { div = sqrt( rowSums(x^2) ); div[ div == 0 ] = 1; return( x/div ); } What is the special meaning for the method name start with a dot? Thank you

Dear list, How can I detect a package is installed or not? If not, then install it. For example, in a script, I want to check the package DESeq is installed or not. If not, then I will using this script to install it. source("http://www.bioconductor.org/biocLite.R") biocLite("DESeq") The pseudo script would be like this: try: library("DESeq") catch:

Dear list, I want to run two independent calculation (A, B) and then combined their results to do a plot in R. Before I just run calculation A first, then calculation B. It will take some times. I just have one server with multiple core. I noticed that there are some nice package in R for parallel calculation, such as parallel, multicore and snow. Also there is a book, O?Reilly ? ?Parallel R,

Hi list, I want to plot two plot in the same figure. I set par(new=TRUE). But it does not work. library(lattice) myPanel <- function(x,...) { panel.histogram(x,alpha=0.4,...) ltext(0.4,1.5,paste("Mean=","0.05",digit=2)),cex=0.8) ltext(0.8,1.5,paste("s.d.=","0.06",digit=2)),cex=0.8) } histogram(sh2,

Dear all Colleague of mine ask me if R is capable of Andrews plot like andrewsplot(x) in Matlab. Quick search did not reveal anything but before I start to write any routine I would like to ask this ingenious audience if there is any implementation of Andrews plots somewhere. I know about parallel coordinate plots in lattice (although I do not use them as I am not sure what the plot tells

Dear list, Is there a elegant way to name multiple ordered plot as A, B, C and D? Just put A, B, C and D on the top left corner of each plot. Usually I do it in Illustrator, but I think in R should there is a way. Could you please provide a example? Thank you very much in advance.

Dear list, I have a dataframe with two column as fellow. > head(dat) V1 V2 0.15624 0.94567 0.26039 0.66442 0.16629 0.97822 0.23474 0.72079 0.11037 0.83760 0.14969 0.91312 I want to get the column V2 mean value based on the bin of column of V1. I write the code as fellow. It works, but I think this is not the elegant way. Any suggestions?
