Re: [R] tcltk, X11 protocol error: Bug?
Dear Nicholas,
This problem has been reported before (enter X11 protocol error on the R
site search at http://finzi.psych.upenn.edu/search.html to see the previous
threads), but as far as I know, there's no definitive explanation or
solution. As well, things appear to work fine, despite the warnings. The way
I handle the problem in the Rcmdr package is simply to intercept the
warnings.
I hope this helps,
John

Subject: [R] tcltk, X11 protocol error: Bug?
Hi,
I am having trouble debugging this one. The code is attached
below, but it seems to be a problem at the C-tk interface. If
I run this 1 time there are no problems if I run it more than
once I start to get warnings that increase in multiples of 11
everytime I run it. Here is a sample session
source(clrramp2.r)
Loading required package: tcltk
Loading Tcl/Tk interface ... done
clrRamp()
tt-clrRamp()
tt
function (n)
{
x - ramp(seq(0, 1, length = n))
rgb(x[, 1], x[, 2], x[, 3], max = 255) }
environment: 0x8b8674c
image(matrix(1:10),col=tt(10))
tt-clrRamp()
There were 22 warnings (use warnings() to see them)
image(matrix(1:10),col=tt(10))
There were 11 warnings (use warnings() to see them)

I am running R-2.1.1 on ubuntu linux 5.04, compiled from
source (not the deb package).
My version of tcl/tk is 8.4. The code is below. If anyone
sees something I am doing foolish let me know, otherwise I
will file a bug report.
