Hi there, I am having some trouble with the Identify() function, it looks that the identify() function only works on the plot of 2-dimension data set. In high-dimension case , if I use pairs() + identify() in hope to observe all the components of the data point I selected, I get error message. Is there anyway to get around this ? Plus, I also need it to actually compare all the

I would like to make one histogram combining two value vectors. One vector has more than 50 entries and the other only has 16. Both vectors contain dates in the POSIXct format. I need to be able to highlight the 16 entries from the smaller data set. Is it possible to do this with the hist function? Which function should I use?

Is there a package (other than xgobi which requires an X server) that will do scatterplot brushing? I see a mention in the mail archive of R-orca by Anthony Rossini but it is not in the current list of packages. My OS is Windows XP version 5.1, service pack 2 R version 2.4.1 (2006-12-18) Thanks [[alternative HTML version deleted]]

Hi everyone, is there a way/package in R that would allow me to select a group of points from a scatterplot by drawing a circle around them or some such? I can use 'identify' to pick individual points, but that gets tedious if one has more than 10-20 spots. I can easily select spots within a rectangle defined by picking points using identify... but a simple rectangle sometimes will

I apologize for the off-topic post, but my Google search did not turn up much and I thought people on this list my have knowledge of this. I am looking for examples of data brushing (i.e. dynmaic linked plots) either on a web site, or in a web-based application, such as an AJAX app. Even better if there is a way to do this in R. Thanks for any help. -Roy M. **********************

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>",

Hi all, I'm trying to create a histogram which shows the frequency of variables within a certain timeframe. I've been using SPSS before, but I didn't quite like it... To describe my problem further here are some example variables: the "event" is actually a string which I recoded using: [code] data$event_class = as.numeric(as.factor(data$event)) [/code] I've recoded
