Dear R users I'm looking for algorithms that assist in spreading out crowded labels, e.g. labels of points in a scatter plot, in order to obtain a nicer visual appearance and better legibility. I'm probably just stuck because I didn't find the right key words for a successful search on the R websites or in the mailing list archives. Any hints are appreciated. Thomas Zumbrunn

Hi all, I'm plotting impulses, where some of them should have labels hovering above them. I know of plotrix' spread.labels function, but would like to save that for instances where there truely is to little space for the label. Does anybody have any hints what' the most efficient way might be to achieve the following: - plot an impulse plot - before placing each of a vector of text

This is to announce that versio 2.0 of the TeachingDemos package is now on CRAN (and hopefully soon to a mirror near you). This is a major upgrade of the package, some of the improvements include: The package now uses an NAMESPACE so it is easier to load just the parts that you need. Some of the GUI demonstrations now use tkrplot so that the graph is in the same window as the controls (there

Hi, I'm dealing with a lattice plot inserted into a tk widget and would like to know when a user has clicked on the plot area of a plot (i.e. inside the axes). For example, library(tkrplot) library(lattice) tt <- tktoplevel() makePlot <- function() print(xyplot(1 ~ 1)) printCoords <- function(x, y) print(c(x, y)) img <- tkrplot(tt, makePlot) tkbind(img, "<1>",

Dear List I am having problems to set text labels in a scatter plot. At some areas dots are close and labels overlap and texts cannot be read. I have too many dots to adjust this manually. Is there any function that will calculate the label offsets to avoid this overlapping problem?

Hello R-list, I am plotting a weighted linear regression in R. The points on my chart are also scaled to sample size, so some points are large, some are small. I have figured out everything I need using the plot() function: how to plot the points, scale them by sample size, weight the linear regression by sample size, plot that line, and plot the labels for the points. However, although the

Hi, all, I would like to know if there is any gui interface out there (academic or commercial) that allows one to edit R-language generated graphs (e.g positioning x axis labels.) It would be nice to have something like the user interface of Igor or Origin. I have already used JGR and R-gui. These are good, but they don't allow one to easily edit graphs. I have also tried
