Hello Everyone, I am an avid Sweave user and I am trying to pretty print floating point numbers for latex output. For example in my document, I would like: 4.2\cdot 10^-{8} Instead of: 4.2e-08 The Hmisc package has a nice function for doing this- but Hmisc has a ton of dependencies and has proved very unportable to the various machines I work on. So, I set out to write my own function that

Hello dear R users, *Here is the background for my question:* I just had a look at the help file for ? Yeast in the "HistData" package. In it, I found a small spelling mistake where the word "*c*istribution" was written instead (so I imagin) "*d*istribution". I thought maybe I should e-mail the developer. Since there is no link to contacting the developer inside

Hi there, I am stuck trying to solve what should be a fairly easy problem. I have a data frame that essentially consists of (ID, time as seqMonth, variable, value) and i want to find the regression coefficient of value vs time for each combination of ID and Variable. I have tried several approaches and none of them seems to work as i expected. For example, i have tried:

I am working on dumping raster data from R into PNG files using rasterImage(). I am working with a test matrix from the rasterImage() example and using it to produce a PNG image with the following code: # From the example for rasterImage(). A 3 pixel by 5 pixel b/w checkerboard. testImage <- as.raster(0:1, nrow=3, ncol=5) testImage [,1] [,2] [,3] [,4] [,5] [1,]

Hi all (especially R-core) I suppose, With the introduction of the new functional programming functions into base I thought I'd ask for a Curry() function. I use a simple one that looks this: Curry = function(FUN,...) { .orig = list(...);function(...) do.call(FUN,c(.orig,list(...))) } This comes in really handy when using say, heatmap():

Hello everybody, here is the code I use to read an excel file containing two rows, one of date, the other of prices: library(RODBC) z <- odbcConnectExcel("SPX_HistoricalData.xls") datas <- sqlFetch(z,"Sheet1") close(z) It works pretty well but the only thing is that the datas stop at row 7530 and I don?t know why datas is a data frame that contains 7531 rows with the

While checking packages against R 2.13.0-beta on Windows, I have run into a few strange error messages related to copying files. The errors all relate to file.copy() and have the form of: Error in Sys.chmod(to[okay], file.info(from[okay])$mode, TRUE) : 'mode' must be of length at least one After half a day of tinkering, the best reproducible example I can come up with involves using

Hi all, I have looked around for help on creating GUIs for R, but haven't found anything. I would be interested in any advice or webpages that have information on the best language, tutorials etc. for creating simple GUIs. Mainly I want to do this as a heuristic exercise. Thanks for any help. Wade Wall [[alternative HTML version deleted]]

Hi, Today I was flabbergasted to see something that looks like a rounding error in the very basic seq function in R. > a = seq(0.1,0.9,by=0.1) > a [1] 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 > a[1] == 0.1 [1] TRUE > a[2] == 0.2 [1] TRUE > a[3] == 0.3 [1] FALSE It turns out that the alternative > a = (1:9)/10 works just fine. Are there any good guides out there on how to deal
