Event handling in R
...LL value from one of the event handlers or for a user-interrupt for it to halt (as per the R manual).
The only way that I've thought of to make this work is using setTimeLimit to kill the function after a set time - here's a (messy) example:
setTimeLimit(cpu = 1)
plot(0, 0)
eventEnv <- getGraphicsEventEnv()
setGraphicsEventHandlers(prompt = 'Test')
while(TRUE)
{
err <- try(q <- getGraphicsEvent(), silent=TRUE)
print(err)
}
# Not run
setTimeLimit(cpu = Inf)
but setTimeLimit doesn't seem to kill getGraphicsEvent() properly, as running this code just ends up with the repeated...

Interactive graphics
...use of
getGraphicsEvent(prompt = "Waiting for input",
???????????????? onMouseDown = NULL, onMouseMove = NULL,
???????????????? onMouseUp = NULL, onKeybd = NULL,
???????????????? onIdle = NULL,
???????????????? consolePrompt = prompt)
setGraphicsEventHandlers(which = dev.cur(), ...)
getGraphicsEventEnv(which = dev.cur())
setGraphicsEventEnv(which = dev.cur(), env)
The problem rises when trying to get interrupts generated by pressing
mouse buttons and, at the same time, interrupts coming from widgets. The
idea is to locate points under a spectrum and draw a baseline.
?In my code the logical se...

Unfixed bugs in latest R-patched
...ack of protection bugs in the equal and greater functions
in sort.c. These bugs are also present in R-2.15.0 and R-3.1.0.
o Fixed lack of protection bugs in the D function in deriv.c.
These bugs are also present in R-2.15.0 and R-3.1.0.
o Fixed argument error-checking bugs in getGraphicsEventEnv and
setGraphicsEventEnv (also present in R-2.15.0 and R-3.1.0).
o Fixed the following bug (also present in R-2.15.0 and R-3.0.2):
x <- t(5)
print (x %*% c(3,4))
print (crossprod(5,c(3,4)))
The call of crossprod produced an error, whereas the...

R 2.12.0 is released
...sed,
sub-architecture: this is useful where different
(sub-)architectures run on the same OS.
? The getGraphicsEvent() mechanism now allows multiple windows to
return graphics events, through the new functions
setGraphicsEventHandlers(), setGraphicsEventEnv(), and
getGraphicsEventEnv(). (Currently implemented in the windows()
and X11() devices.)
? tools::texi2dvi() gains an index argument, mainly for use by R
CMD Rd2pdf.
It avoids the use of texindy by texinfo's texi2dvi >= 1.157,
since that does not emulate 'makeindex' well enough...
