Empirical cumulative distribution with censored data
Dear list,
I would like to plot the empirical cumulative distribution of the time
needed by a treatment to attain a certain goal. A number of
experiments is run with a strict time limit. In some experiments the
goal is attained before the time limit, in other experiments time
expires before the goal is attained. The situation is very similar to
survivial analysis with censored data. I tryed

Multiple comparisons in a non parametric case
Dear all,
I am conducting a full factorial analysis. I have one factor consisting
in algorithms, which I consider my treatments, and another factor made
of the problems I want to solve. For each problem I obtain a response
variable which is stochastic. I replicate the measure of this response
value 10 times.
When I apply ANOVA the assumptions do not hold, hence I must rely on non
parametric

Passing arguments to panels in trellis plots

I am trying to produce survfit plots in a trellis environment and I
would like the plots to be logarithmic.
I am trying this:

panel=function(x,groups,subscripts)

variable number of variables in data frames
I would like to specify that certain columns in a data frame should be
treated as ordered factors. I know what numbers these columns are, but
not their names.
How do I do this?
For example, if I know columns 1:4 are to be treated as factors, I can
write
dat <- matrix(c(2,1,1,1, 1,1,1,1), 2, 4)
D <- as.data.frame(dat)
# force all variables to be treated as binary

How to auto-scale cex of y-axis labels in lattice dotplot?
When I create a dotplot in lattice, I frequently observe overplotting
of the labels along the vertical axis. On my screen, this illustrates
overplotting of the letters:
windows()
reps=6
dat=data.frame(let=rep(letters,each=reps), grp=rep(1:reps, 26),
y=runif(26*reps))
dotplot(let~y|grp, dat)
Is there a way to automatically scale the labels so that they are not
over-plotted?

dotplot: character size of labels (PR#816)
There seems to be a bug in "dotplot" concerning the "cex" parameter. Setting
cex has no effect on the character size of the labels of the points.
This problem was posted to r-help today (Thu, 18 Jan 2001); the solution
given by Brian Ripley (and Uwe Ligges) seems to work for me.

RE: Text Rotation (was: Take care with codes()!)
You can use the graphics parameter "srt" to rotate displayed text by a
specified number of degrees, e.g. srt=45 to put it on an angle, srt=90 to
put it vertical.
If you do this, may need to modify the call to text to increase ylim and
change the plot location to give you more room.
I'm working to update the 'balloonplot' function in the gregmisc package now

RE: Text Rotation (was: Take care with codes()!)
I've just uploaded gregmisc_0.8.2.tar.gz to CRAN. It should show up in the
package repository in a day or two.
This version of the gregmisc package provides an enhanced 'balloonplot'
function with 'rowsrt', 'colsrt' arguments to control rotation of the
labels, and 'rowmar', 'colmar' to control the amount of space reserved for
the labels.

Is glm weird or am I?
Hi,
I've written a script that checks all bivariate correlations for
variables in a matrix. I'm now trying to run a logistic regression on
each pair (x,y) where y is a factor with 2 levels. I don't know how (or
whether I want) to try to fathom what's up with glm.
What I wrote is attached. Here's what I get.

No subject
Normally `codes' is not the appropriate function to use with an
unordered factor. Use `unclass' or `as.numeric' to extract the
codes used in the internal representation of the factor, as these
do not assume that the codes are sorted.
and this is one of the `normally' cases. Your code will only work
correctly if the levels are in alphabetical order (in the locale

persuade tabulate function to count NAs in a data frame
Hi,
I'd like to ask you a question again. It is basically about data frames, NAs and tabulate function.
I have this data frame. I already used this in one of the previous questions of mine. It intentionally looks this simple, my real 'df' dataframe is much bigger actually and again, I am not willing to annoy anyone with huge databases... So, my database:

Wrong df in bartlett.test when subsetting data (PR#1124)
Full_Name: Jens Lund
Version: 1.3.1
OS: Windows
Submission from: (NULL) (194.239.194.210)
When we subset a dataset bartlett.test does not calculate the df correctly:
X <- rnorm(50) # Generate simulated samples
f <- gl(10,5) # Generate a factor with 10 levels and
# 5 replications of each level
# Works correctly

I've written a piece of code (see below) to do a wavelet image
decomposition, during the evaluation of this code I would like to write
the results of some calculations back to the R root directory. I used
assign() to do so because the names should vary when going thrue a

setting the legend scale in contour plots
Hi,
I'd like to compare SST data for year 2000 with SST for year 2001. I managed
to get filled contour plots showing monthly SST for both years (12 plots for
each year, 24 plots in total). In order to compare year 2000 and year 2001,
however, I'd need to have the same legend scale (same color bar) in both
years plots.
Thus, my question is: is there a way to set the legend scale in
