I've done a little snooping around the R Gallery Site (http://addictedtor.free.fr/graphiques/) and the "Statistics with R" site (http://zoonek2.free.fr/UNIX/48_R/all.html), but I can't seem to find what I'm looking for.  Here is the type of plot I would like to draw: (1) 2-D three axis plot where each axis is separated by 120-degrees (would be great if the number of axis

Dear R helpers Reproducible example: #warning - this causes a hard freeze on the machines I've tried it on matrix.holder<- matrix(rnorm(150), nrow=30, ncol=5) Out= expand.grid(matrix.holder[,1],matrix.holder[,2],matrix.holder[,3],matrix.holder[,4], matrix.holder[,5]) Problem: I'm running an analysis that I would like to do using a matrix containing all the possible combinations of

Hi everyone, I am writing a simple script to read in a data file, search through the data file for an exact character match for a microRNA name, subset those rows, and aggregrate a dataframe with those subselections all in a for loop. This is what I have so far: #READ IN DATA file1 = "C:/Desktop/mirtarget2_predictions.txt" data = read.table(file1, header=FALSE, sep="\t")

Is there a place that shows how to create two plots that are stacked on top of each other where they share a common x-axis scale, but have differnt y-axis scale? Say have the following data: airquality Stack plot(airquality$Day, airquality$Wind) on top of plot(airquality$Day, airquality$Temp). I am interested in stacking the two on top of each other with no seam, or plotting the two lines with

I did some btrfs RTFS over the weeking and I have a hard time understanding what this code is attempting to do: 28 int btrfs_tree_lock(struct extent_buffer *eb) 29 { 30 int i; 31 32 if (mutex_trylock(&eb->mutex)) 33 return 0; 34 for (i = 0; i < 512; i++) { 35 cpu_relax(); 36 if

How can I add an overall plot title to these four plots? I would like to have something that says, "Distribution Comparisons": par(mfrow = c(2, 2)) # Plot 1 plot(rnorm(10),type="l",col="red") title(main = list(paste("Normal"), ????????????????????????? col="black", cex = 1.0)) # Plot 2 plot(rpois(10,
