Folks: I have found R's fewWindoze GUI Widgets (like winDialog, choose.files,winMenuAdd etc.) to be quite useful in building simple but functional interfaces (I hesitate to call them GUI's) for one-off applications for non-R users. It's quite easy for me to write statistical "solutions" in R, slap on a little GUI that allows users access to the functionality, and then

Hello R-helpers I want to put a color scale in a plot: I've got an xy plot where the values of the response (z=f(x,y)) is symbolically given by colors (like heat or rainbow color scale) I would like to put such a scale with apprpriates labels in the plot, so as to facilitate the interpretation (like in a finite elements result plot) How is taht possible? Thanks Anne [[alternative

Newbies (and others!) may find useful the R Reference Card made available by Tom Short and Rpad at http://www.rpad.org/Rpad/Rpad-refcard.pdf or through the "Contributed" link on CRAN (where some other reference cards are also linked). It categorizes and organizes a bunch of R's basic, most used functions so that they can be easily found. For example, paste() is under the

Peter You question is difficult to answer without more information about the distribution of your residuals. Different residual patterns call for different transformations to stabilize the variance. One very common form of heterocedasticity is increasing variance with increasing values of an independent predictor, i.e. the variance of the residuals of y=x increase as x increases. In this case a

R listers: I have been foiled by plotmath! (in R 2.01,Windows 2000) The task: Plot a normal density and label the ticks as mu - 3 sigma, mu - 2 sigma, ...., mu + 3 sigma, where the mu's and sigmas appear as Greek symbols, of course. The following code does this: x<-seq(-3,to=3,by=.01) y<-dnorm(x) plot(x,y,type='h',col='lightblue',axes=FALSE)

I would like to use the function winDialogString to get input from a user to a program but would like to eliminate the cancel button option and just have the OK button appear. The problem is that if a user enters data then accidently hits Cancel instead of OK, the program may either run incorrectly or quit due to the error of having NULL for a variable. I can think of some unsophisticated ways

R 2.0.0 patched under win2000. MS Office Excel 2003. ODBC Drivers? This may not come as a surprise -- sqlFetch() (and perhaps other ?) appear not to handle table/worksheet names with spaces in them in Excel tables. I was not able to find documentation that specifically mentioned this, although the Help pages vaguely hinted that there might be difficulty with Excel's "peculiar

Can someone please explain to me why the dates get shifted by one day when I create an its ( irregular time-series ) object from a matrix for which I've assigned row names. E.g. in the example run below, why does the its object have dates one-shifted from my original dates? > install.packages('its') > install.packages('Hmisc') > require(its) > m <-

Folks: The "key" argument of trellis commands (e.g. xyplot()) allows one to place a key at the top of a trellis display using key=list(space='top',...) I would like to increase the space between the bottom of the key and the trellis plots beyond the default. Is there a simple way to do this? At present, I add an empty row (e.g. text = '', point colored in background

Hi, How can I read data of unequal number of observations (rows) as is (i.e. without introducing NA for columns of less observations than the maximum. Example: A B C D 1 10 1 12 2 10 3 12 3 10 4 12 4 10 5 10 Thanks in advance. Sachin --------------------------------- [[alternative HTML version deleted]]

To R-Developers: I wish to report what I believe are inconsistencies between Green Book descriptions and R methods behaviors. I **realize** that R does not guarantee total consistency with the Green Book; therefore I leave it to you to decide whether any of this is a bug, design choice, or a need for additional documentation -- or whether I have simply misread or overlooked existing explanations.
