I feel like an idiot posting this because every language I've ever seen has a string function that trims blanks off strings (off the front or back or both). Ideally, it would process whole data frames/matrices etc but I don't even see one that processes a single string. But I've searched and I don't even see that. There's a strtrim function but it does something completely

...ncentric half-circles. (Because I want to communicate information about the diameters-- half-circles are sufficient to show diameters AND they leave ample room to one side of the figure to label the circles' diameter measurements.) What should I do? Thank you for your help, Alexis Diamond adiamond at fas.harvard.edu

...dian. I asked John about it and he doesn't know what the properties of this weighted Levene test would be. Does anyone have any thoughts or suggestions, or know of a robust weighted hypothesis test for equality of variances? Thank you in advance for any advice you can provide, Alexis Diamond adiamond@fas.harvard.edu [[alternative HTML version deleted]]

hi, i'm trying to learn how to use aregImpute by doing the examples provided with the package, and after installing Hmisc.1.6-1.zip (for Windows), and running the very first example on R 1.7.1, i get an error message warning me about "mace" (see below) and acepack. i found the acepack package, but its filename ends in tar.gz and i'm finding it difficult to open (because its

...as i guess they're also called). as a quick fix, i've also tried changing the color of the whiskers to the background color to make the whiskers invisible, but this doesn't work well when the whiskers perfectly align with the border of the box. thank you for your help, alexis diamond adiamond at fas.harvard.edu ### my.panel, the function that I've been told can suppress whiskers, ### when outline = F my.panel <- function(x, y, box.ratio = 1, font = box.dot$font, pch = box.dot$pch, cex = box.dot$cex, col = box.dot$col, outline = T, ...) { ok <- !is.na(x) & !is.na(y)...

Hi, one of the nice things about contour is that it labels all contour lines. contourplot only labels each particular elevation a single time. i.e., if there are two contour lines corresponding to z = 45, it will only label one of them. is there a way to get contourplot to automatically label all the contour lines, even those that are repeated? i ask because i want to plot contour plots *w/

Dear R-list, i have 6 different sets of samples. Each sample has about 5000 observations, with each observation comprised of 150 baseline covariates (X), 125 of which are dichotomous. Roughly 20% of the observations in each sample are "treatment" and the rest are "control" units. i am doing propensity score matching, i have already estimated propensity scores(predicted

Dear R Community: I am working on a public health early warning system, and I see that the qcc package allows for CUSUM and other statistical quality tests but I am not sure if my project is a good match for qcc functions as written. Any advice you may have is very much appreciated. I have four years worth of daily counts of emergency room admissions for different conditions (e.g. respiratory,

Hi, I've got a wireframe 3D surface plot, but I don't want a frame around it. Is there any way to remove the frame, or (worst case) change the color of the frame to the background color (which looks like grey). I'm using ver 1.7.1 I've tried frame.plot = F, but that doesn't seem to work for 'wireframe'. Many thanks, Alexis Diamond

hello R-world, according to the strucchange package .pdf, "all procedures in this package are concerned with testing or assessing deviations from stability in the classical linear regression model." i'd like to test/assess deviations from stability in the Poisson model. is there a way to modify the strucchange package to suit my purposes, or should i use be using another

I have a data.frame with rownames taken from a database. Unfortunately, one of the rownames (automatically obtained from the DB) is an empty string. I often do computations on the DB s.t. the answers (rows) are indexed with respect to the rownames so a computation on a DB record might necessitate the indexing into the data.frame by the emtpy row name. Unfortunately, that doesn't seem to

I know that I'm a fool for trying to get this working under windows but I'm obliged. Note I have R 2.6.1 and the latest cygwin.
