Dear list, I am trying to plot the local variance in a moving window on a dataset. The function that I am trying to use for this is wapply from gtools. However, from the lattice panel function code: <snip> cat(x) cat(y) wapply(x,y,method="range",width=1/10,fun=sd,na.rm=TRUE) -> outvar </snip> I get: <snip> 109 109 109 109 109 109 116 116 116 116 119 119 123

I have some Bernoulli data something like this: x<-sort(runif(100,1,20)) p<-pnorm(x,10,3) y<-as.numeric(runif(x)<p) plot(x,y) lines(x,p) This plot is not very satisfactory because the ogive does not visually fit the (0,1) points very well, and also because the points tend to fall on top of one another. The second problem can be eliminated by adding vertical jitter. However I was

This one has me a bit stumped, and I know there may well be a really simple way of doing it in R. Sorry for the long-winded explanation. Short version: given an array of arbitrary number of dimensions D, how can we retrieve the Nth element of dimension D without knowing in advance what D will be? For example, given that array A has dimensions c(3,4,5), and N=2, can we write a function that

Version 0.8.0 of the gregmisc package is now (or will shortly be) available on CRAN. New in this release: - Enhanced and bug-fixed 'CrossTable' function (contributed by Marc Schwartz) - Augmented the 'barplot2' function with an 'add' argument to allow for the addition of a barplot to an existing graphic. (contributed by Marc Schwartz) - Added the

I am having difficulty installing packages. For example, here I have tried to install "gplots" but to no avail. I have tried multiple mirrors and different packages (errbar) but after installation I seem to be unable to access any of the commands or help pages. I am a little concerned about the 'lib' missing message but this has been present for previous successful package

Dear all, I am a newbie in R. I encounter a problem as follows. I have 2 vectors X and Y that have a equal length of several thousand. I see Y as the function of X. Both of them are random. X is not arrranged in any order. Of course, I do plot(X,Y). Now, I want to use a sliding narrow window to run over each X, then calculate the variances within that window. Anyone knows easy way in R to do

Hey there I have two vectors: y<- c(0.4, 0.0, 0.2, -0.2, -0.6, 0.2, 0.0, 0.0, 0.4, 0.4, 0.2) In the vector y, I want to access (in the order given) all of the values in between each of the specific values of given. I understand subsetting with y[i], but how do I get to ssomewhere in between -0.6 and 0.2? Thanks Eric Jennings matheric at myuw.net

I have two vectors x and y, which I would like to plot against each other. I am also displaying other data in this plot. However, I have about 1 million points to plot, and just plotting them x againt y is not very informative. What I'd like to do is to do sort of a continuous box plot. My x values goes from -1 to 1 and my y values from 0 to 1, so I?d like to plot the median and quantiles,

Hello, I was wondering wether there's a function in R that takes two vectors (of same length) as input and computes mean values for bins (intervals) or even a sliding window over these vectros. I've several x/y data set (input/response) that I'd like plot together. Say the x-data for one data set goes from -5 to 14 with 12,000 values, then I'd like to bin the x-vector in steps of
