I have been using ddply to do aggregation, and I frequently define a single aggregation function that I use to aggregate over different groups. For example, require(plyr) dat <- data.frame(x = sample(3, 100, replace=TRUE), y = sample(3, 100, replace = TRUE), z = rnorm(100)) f <- function(x) { data.frame(mean.z = mean(x$z), sd.z = sd(x$z)) } ddply(dat, "x", f) ddply(dat,

Is there an easy way to "thin" a lattice plot? I often create plots from large data sets, and use the "pdf" command to save them to a file, but the resulting files can be huge, because every point in the underlying dataset is rendered in the plot, even though it isn't possible to see that much detail. For example: require(Hmisc) x <- rnorm(1e6)

I'm trying to use lattice graphics to produce some small plots for inclusion in a LaTeX file. I want the LaTeX fonts to be used in the plots, but to be scaled down to match the size of the plot. I have written the following code to apply a scaling factor to all the "cex" and "padding" entries in the trellis parameters, but there is still a large white space between the key

I'm trying to make multiple line plots, each with a different color, using the xyplot command. Specifically, I have an NxK matrix Y and an Nx1 matrix x. I would like the plot to contain a line for each (x, Y[,i]), i=1:K. I know something like xyplot(Y[,1] + Y[,2] + Y[,3] ~ x, type='l') will work, but if Y is large, this notation can get very awkward. Is there a way to do something

I'm having some trouble using the latticeExtra 'combineLimits' function with a Date x-variable: require(lattice) set.seed(12345) dates <- seq(as.Date("2011-01-01"), as.Date("2011-12-31"), "days") dat <- data.frame(d = rep(dates, 4), g = factor(rep(rep(c(1,2), each = length(dates)), 2)), h =

I'm trying to create an xyplot with a "groups" argument where the y-variable is the cumsum of the values stored in the input data frame. I almost have it, but I can't get it to automatically adjust the y-axis scale. How do I get the y-axis to automatically scale as it would have if the cumsum values had been stored in the data frame? Here is the code I have so far:

When using the 'splom' function of the 'lattice' packge, is it possible to get all the tick marks in the outer margins of the plot? X <- as.data.frame(matrix(rnorm(1000), 100, 10)) plot(X) ## Tick marks are in the outer margin splom(X) ## Tick marks are inside the on-diagonal panels Thanks. - Elliot [[alternative HTML version deleted]]

I'm trying to write a generic function that calls different methods depending on the structure of the argument, but not the exact type of its contents. For example, the function 'nan2last' below works for a numeric vector but not for a vector of Date objects. Is there any way to make it work on any vector? setGeneric("nan2last", function(x) {

Is it possible to get R to report the line number of an error when a script is called with source()? I found the following post from 2009, but it's not clear to me if this ever made it into the release version: ws wrote: >* Is there a way to have R return the line number in a script when it errors out? *>* *>* I call my script like: *>* *>* $ R --vanilla < script.R >

Hi, I'm not sure this is a bug, so I thought I'd bounce it off the help group first. I had a dataset which I was subsetting, and occasionally I get an empty subset. If I don't check for emptiness and go straight to a which.min call on the subset, the program gets a big negative number back. One-line Example: > which.max(NULL) [1] -2147483647 This caused an indexing

Hi Elliot, I couldn't find anything related to smbpasswd expiry. Since u have "unix password sync = true", just a wild guess, if u could turn off password ageing in unix passwd file (man passwd for more detail) and see if problem persists.

Hi all, I keep running into a small problem in my programming, and I'm sure there's an elegant way around it... I often want to use apply() on a matrix with a variable number of columns. It works just fine unless the number of columns is one, in which case the matrix becomes a vector, and apply() complains. Example below: ----------------------------- a.matrix <- matrix(rnorm(6),

Hello! I am having an odd problem in that when the caller dials extension "2" in a dialplan, the system waits 3 to 4 seconds before proceeding. This doesn't happen when any other other extensions are dialed, including an identical dialplan on other another extension! Is this a bug? Later, Elliot

Hi just a quick question in which I must use the "function and return" part of R. If I was asked to define a function called "median" where the function has a single argument x and returns the median value of a vector. How would I go about saying the median = element x in terms of n (say (n + 1)/2 or whatever it would be) if there is an even amount of elements, or x in terms
