In the below code fragment, print(arg) always prints the last element of rekeningen$rekening. Is this because of lazy evaluation? I.e. arg is evaluated at the time the button is pressed? And, if so, how can I avoid this? I tried function() {force(arg); print(arg)} but that didn't work either. Thanks, Jeebee. for(rek in seq(1,nrow(rekeningen))) { arg <- rekeningen$rekening[rek]

Dear all, Based on my question a few months ago https://stat.ethz.ch/pipermail/r-help/2006-January/086952.html and solved with https://stat.ethz.ch/pipermail/r-help/2006-January/086955.html https://stat.ethz.ch/pipermail/r-help/2006-January/086956.html and from https://stat.ethz.ch/pipermail/r-help/2006-January/086958.html frac.fun <- function(x, den){ dec <- seq(0, den) / den nams

I intend to draw a plot of y against x. In the background of this graph I wish to creat a histogram of the horizontal variable x. Does any expert know how to produce such a plot? [[alternative HTML version deleted]]

Dear R-list, I'm iterating several calls to plotCI [gplots], like so: plotCI( x = xvals.f[sorted], y = yvals.f[sorted], xlim = c(xmin, xmax), ylim = c(ymin, ymax), pch = plot_symbols[graph_idx], type = "b", lty = plot_linetypes[1], col = plot_colors[graph_idx], barcol = plot_colors[graph_idx], uiw = NA, xlab = "", ylab = "", add =

I've found several similar issues with write.table/read.table with Dates on this list, but trying to follow this advice I still get an error. First, I read in data from several files, constructing several date/time columns using ISOdatetime > str(Tall$Begin) 'POSIXct', format: chr [1:40114] "2005-10-02 00:00:00" "2005-10-02 00:00:00" ... > length(Tall$Begin)

Hi List, Is it possible to tell R to use tcl/tk 8.5? My R package seems to depend on libtcl8.4.so. However, in Windows it seems to be possible to set TCL_LIBRARY and MY_TCLTK. Is there something similar possible in Linux? I have installed: $ rpm -q R R-2.3.1-1.fc5 $ locate libtcl8 /usr/lib/libtcl8.4.so /usr/local/lib/libtcl8.5.so

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause. Thanks very much, JeeBee. require(tcltk) || stop("Package tcltk is not available.") # Add path to

Hi all, This might be a little off-topic, but I wanted to let you all know about a project for which I used R. I started an (free for all, open source) offline banking tool, programmed in R and using the tcltk library for the user interface. It has several nice features already :) It can use regular expressions to match/group bank transactions and can obviously use R's power to plot nice

Dear list, I have multiple (BWidget) listboxes in the same toplevel window. The problem is, if I select (by left clicking) on one of those listbox elements, the current selection in the *other* listboxes is cleared! Anybody knows how I can prevent this? Here's my code (sorry not complete): (E.g. If I select an X value, I'd lose the Y value I selected before) gui.create.tab.general <-

Dear list, I (running fedora core 5 linux) have a native Windows (actually do not know which windows version) dll file, in which are functions I want to call in my Linux program. That is why I installed wine, to see whether I could make this work :) I know exactly what functions are in the dll, what their prototypes are, but I do not have the source, only the myfile.dll. Now, what I don't

Can anyone tell me how I can supply more than one graph to plotCI (gplots) at once? Below is what I tried, also with rbind instead of cbind. What is the way to do this (in general, I think)? Problem is that lines of 1-st and 2-nd series are mixed, while they have nothing to do with each other. I also tried calling plotCI with argument add=TRUE, which didn't seem to work (that is actually

Hi all, I've been reading about aov() at http://www.psych.upenn.edu/~baron/rpsych/rpsych.html and http://davidmlane.com/hyperstat/intro_ANOVA.html and I try to use this test in experiments with my simulator. What I would like Anova to tell me is whether the differences I see when plotting the means of performance per method are significant. And also, whether this is dependent on the problem
