Qt device update
...al. For those interested, It can be downloaded from http://dsarkar.fhcrc.org/R/R-Qt.html I have a couple of related questions. First, dev.interactive(), used in example() and many demo()-s to decide if the current device is interactive, is currently implemented as: > dev.interactive function (orNone = FALSE) { iDevs <- c("X11", "GTK", "gnome", "quartz", "windows", "JavaGD") interactive() && (.Device %in% iDevs || (orNone && .Device == "null device" && getOption("device") %...

example(..., ask=getOption("example.ask"))
...ultiple (20-30!) PNG files using png()/dev.off(). I noticed that I get a "Hit <Return> to see next plot:" for each png() call, when calling example() [interactively]. The code for example() has: if (ask == "default") ask <- echo && dev.interactive(orNone = TRUE) if (ask) { if (.Device != "null device") { opar <- par(ask = TRUE) on.exit(par(opar)) } op <- options(par.ask.default = TRUE) on.exit(options(op), add = TRUE) } When calling example() interactively, either with...

plot slideshow
Dear R experts: I've seen that it's possible to make a sort of "slideshow" with several R-plots (each slide is activated by a click on the mouse). How can I put this on a R-script??? Regards. D. [[alternative HTML version deleted]]

R-2.4.0 is released
...ppropriate. o data.frame() has a new argument 'stringsAsFactor'. This and the default for read.table(as.is=) are set from the new global option 'stringsAsFactors' via the utility function default.stringsAsFactors(). o dev.interactive() now has an optional argument 'orNone'. o df() now has a noncentrality argument 'ncp', based on a contribution by Peter Ruckdeschel. o example() gains an argument 'ask' which defaults to "TRUE when sensible", but the default can be overridden by setting option 'example.ask'. o exp...

t.test in a loop
Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems
