similar to: Max/Min w/ Non-linear constraints

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 all, Just a random shot in the dark. Does anyone have/know of a function for the CDF of a generalized error dist? -- Elliot Williams (ewilliams at ucsd.edu) Economics Department, UC San Diego -------------- next part -------------- An embedded message was scrubbed...

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),

Hi all, I'm having a very minor problem. Most every time I use the pager (I think) I get the following error about character 32. It works fine, but the error is a bit annoying. > ?version sh: invalid character 32 in exportstr for export R_NSIZE sh: invalid character 32 in exportstr for export R_VSIZE R.Version package:base R Documentation (and then the

Hi all, I'm making an animation of a rotating persp plot of some data. It's easy, really: I just plot the persp in a loop over the theta parameter, saving each plot, and then chain them together with ImageMagick (as suggested on Paul Johnson's R-tips page). But... when you run the animation, because each graph is individually re-scaled, the image is not the same size in each

Hello again, A different but related question to my last one: Does anyone know if one can easily estimate state-space models using ML and the kalman filter using R? I would be especially interested in a relatively flexible function that would allow for estimation of hyperparameters, or could be made to do so. Thanks Michael J.

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.

I'm attempting to update to R 2.15.1, and I'm having trouble with a package that depends on the "Matrix" package. I've created a dummy package consisting only of a DESCRIPTION file that specifies the dependence on "Matrix", a NAMESPACE file, and an R directory, containing a single function, "square <- function(x) { return (x*x) }". When I try to

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 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 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

Hi R-devel, [Question]: * Is there a KEYWORDS file to lookup 'keywords' to supply the vignette command, '\VignetteKeywords{}'? -or, is the pkg writer free to tag the vignette using any keywords he/she chooses? i.e., free-tagging.
