How to still processing despite bug errors?
Hi, everybody.
I am working processing EEG data from 1000 pacients. I have a specific
syntax to perform the Spectral Analysis and a loop to analyse all subjects.
each subject data are in separate folders (P1, P2 P3...)
My question is: in some cases, some errors can appear in one subject. I want
to know if is possible to jump to the next subject and perform the same
syntax , exibiting an error

R-beta: S Compatibility (again)
While I think total compatibility is not possible or even very
important I have become aware recently of some fairly low level
incompatibilities that have rather serious consequences for
interchange between systems. Some of these are possibly well
known, but I put them on on record here just in case. (I do not
expect any action on these, of course, but people may want to
note them, and correct

Own classes in "histogram"
Hi,
I try to make a histogram from a variable that contains the number of
shoots from about 1000 individuals from a specific plant species (the range is 1-110).
Those numbers are highly skewed to the right.
My question is: how can I make my own classes with the lattice
"histogram"?
I tried it with "breaks=c(0,5,10,15,20,25,110)" but my "25-110"-class is presented

Re: diamond graphs, patents and rootograms
Talking about Excel, you can produce excellent graphs in Excel. Yes you
have to work at it, but you can get there. The problem is that they are
not the default. My gut feeling is that R will make more of an impact in
the presentation of graphics than any implementation in Excel.
So even if a patent were granted and it made itself into a mainstream
package, would it change the world or would the

how to plot chi-square distribution in the graph
if i want to plot the chi-square distribution with a different degree of
freedom how can i plot it in the graph?Sometimes i plot the histogram and
cut it in a lot of piece.It's distribution like a chi-square.So i want to
plot the chi-square with a different degree of freedom to compare it .

convolution of the double exponential distribution
Is there any R function that computes the convolution of the double
exponential distribution?
If not, is there a good way to integrate ((q+x)^n)*exp(-2x) over x from
0 to Inf for any value of q and for any positive integer n? I need to
perform the integration within a function with q and n as arguments. The
function integrate() is giving me this message:

using user-supplied derivatives in rgenoud
I have been using the rgenoud package for a nonlinear least-squares
problem with lots of local minima, and it works very well but takes lots
of time. According to the article refrenced in the documentation, the
original GENOUD-software by the same authors seems to allow for
user-supplied analytical derivatives instead of numerical approximations,
which would probably save some time. Does anybody

Violin plot for discrete variables.
Dear Rgurus,
To my knowledge the best way to visualize the distribution of a discrete
variable X is
plot(table(X))
The problem which I have is the following. I have to discrete variables
X and Y which distribution I would like to compare. To overlay the
distribution of Y with lines(table(Y)) gives not satisfying results.
This is the same in case of using density or histogram.
Hence, I am

getGraphicsEvent() alternative for cairo graphics device?
Hi all,
I'm writing an interactive plotting function for viewing fMRI
datasets. Currently, I get keypresses using
grDevices::getGraphicsEvent().
Unfortunately getGraphicsEvent() only supports the X11(type="Xlib")
graphics device on Unix systems. The Xlib device doesn't support
buffering (i.e. dev.hold() and dev.flush()), so redrawing the plots
causes lots of flickering.
Is

getGraphicsEvent() alternative for cairo graphics device?
Hi
The current status is that I am keen for people to contribute some
testing code (see https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951)
There were also some getGraphicsEvent() changes/fixes suggested by
Richard Bodewits (cc'ed), for which I am also seeking test code.
