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> 109 109 109 109 109 109 116 116 116 116 119 119 123 123 123 123 127 127 133 133 133 133 13...

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

...d N=2, can we write a function that will "know" to return A[,,2], and not mistake that for A[2] or A[,2]? Bonus question - can such a function be written without relying purely on an arbitrarily high number of "if" statements? Long version: I've been using Greg Warnes' wapply function (thanks Greg!), and modifying it to suit my own ends. wapply() takes a vector, and repeatedly applies a function FUNC (decided at run-time) to windows of the data. The modification I've made is to generalize the return structures - if a scalar is returned by FUNC, wapply returns a v...

...t. - Enabled fit.contrast for lme object now that Doug Bates has provided the necessary support for contrasts in the nlme package. (Thanks Doug!) Requires the newly released nlme 3.1-37. - 'make.contrasts' has been augmented to check for too many submitted contrast rows - Updated wapply.R to allow specification of evaluation points when method is 'width' or 'range' using the 'pts' argument. - Updated wapply.Rd to add 'pts' argument - Fixed typos, spelling errors, grammatical errors and lack of clarity in various help pages.

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
