Hi, I am working under Windows and I am using R2.11 I want to use tkscale in my GUI. As the interval is quite big, I can't set the scale to a certain specific value. Therefore I want to add tkentry to allow the user to set tkscale to a certain value. Here is the code library(tcltk) tt<-tktoplevel() tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label=&quo...

Hi, I have a large plot that I would like to display in a graphics device with scroll bars. I therefore decided to use the windows function like so... mag<- length(tick) windows(height=mag/8, width=10, rescale="fixed") However, when I use the scroll bars the device (i guess) is re-drawing the plot. Is there any way in which I can get it to 'smooth scroll'? Kind regards,

Hello everybody, I am wondering if it is possible to create a gui to plot a time series that is very big, it's an EEG signal of 20mins. What I would like to do is plot the first 5mins, then have a button on the gui that plots the next 5mins when pushed. Is it possible? Thanks in advance ! Gael.

Dear R users graphing with plot(x) seams to work for a small length(x), when length(x) is too large it seams to clutter the display, a solution would be to display subsets of x at a time, yet a better way which I hope R supports is to place a sliding bar on the display window to control length(x) and thus the resolution, which will involve auto scaling the y axis as well as automatically

Dear R-help list members, I'm writing a package using tcltk. Thanks to Peter Dalgaard's excellent work on the tcltk package, almost everything has gone very smoothly. I'm stymied, however, by the following problem: I want to incorporate a bitmap image, stored as an xbm file, in a widget. To take a simple example, top <- tktoplevel() tkgrid(tklabel(top,

Hello I have data in many files in a directory, how can I loop through the files in a given dir in-order-to build a data.frame? thanks

Dear all R gurus, I have following syntax: y = c(1:10) chippy <- function(x) { y[5] = x sin(cos(t(y)%*%y)*exp(-t(y)%*%y/2)) } curve(chippy, 1, 20, n=200) But I am getting error while executing : Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ In addition: Warning message: number of items to

Hi All, I am currently preparing some form of slideshow introducing R and its capabilities for some colleagues. The thing will be about 30 mins, and I'd like to have some "pretty pictures" and some "amazing facts" (I'm trying to sell, obviously :)). Can I ask if it's possible to easily retrieve a gross figure of the number of functions in R considering the

A common process when data is obtained in an Excel spreadsheet is to save the spreadsheet as a .csv file then read it into R. Experienced users might have learned to be wary of dates (as I have) but possibly have not experienced what just happened to me. I thought I might just share it with r-help as a cautionary tale. I received an Excel file giving patient details. Each patient had an ID
