boxplot label cleanup
The boxplot below is close to what I would like, but needs some clean up.
I've been unable to address the following:
1) How can I use the full extent of the plot space (there is white space on
either side of the data)?
2) How can I reduce the # of month labels (e.g. every 3rd month Jan Mar
Jun...) but still keep them staggered?
3) The year labels at the top of the plot have been positioned

Population pyramids
Hi, I hope somebody can help me with this issue: I am doing population pyramids using the barplot command, so in the left side I have male age structure and in the right side the female age structure. To plot the male age structure I put the data in negative numbers. Now, I want to change the sign in the bar plot in such way that I have no-sign numbers, both in left and right side of the graph. I

kernlab sigest
hello,
I have the following problem setting parameter 'frac' in the sigest
function of the kernlab package.
## executing the ?sigest example:
library(kernlab)
data(spam)
srange <- sigest(type~.,data = spam)
## works fine...
## setting 'frac' explicitly

Problem with mathematical expression and loop
Hi to all
I use a loop to plot 9 different histograms of 9 different
transformations of one dataset (x).
I want to label the histograms with the mathematical expression of each
transformation (e.g. x^3). For that I've prepared a vector with the
labeling names for "expression".

isohybrid and ISO images whose size is not a multiple of 2048 bytes vs. VirtualBox
Hi,
my proposal is based on a mathematical proof (see mail
before) and yours is correct too. They cannot but match.
Let's inspect your examples:

This are exactly 132 cylinders of 255x63.
132 is divisible by 4. So there is no padding needed.

Hi friends - I'm plotting a ratio of bicarbonates i ggplot2 and
ylab(expression(paste(frac("additive BIC","true BIC")))) worked OK - but
now I have been asked to put the chemistry instead - so I wrote

- and frac saw that as additive = numerator and HCO3- =

lattice xyplot strip colors and location
Hi all,
I've been trying (unsuccessfully) to modify an xyplot I created using the lattice package. I would like to change default strip colors and locations.
I started with numeric data in 4 columns, which look like this:
0.25 2 1 32
0.25 2 2 30
0.25 2 3 27
0.25 2 4 23

CI wiskers
I have a matrix containing means and CIs (lower and upper in two columns, so
three columns for every data point) for several points. I have to build a
graph of these means accompained by the CIs (as wiskers). No problems with
making the graph of means, but I don't know how to introduce CIs.
Can anybody advise?

how to make plotmath expression work together with paste
Recent questions about using plotmath have renewed my interest in this question
I want to have expressions take values of variables from the
environment. I am able to use expressions, and I am able to use paste
to put text and values of variables into
plots. But the two things just won't work together.
Here is some example code that shows what I mean.

maxLik pakage
Hi all;
I recently have been used 'maxLik' function for maximizing G2StNV178 function with gradient function gradlik; for receiving this goal, I write the following program; but I have been seen an error in calling gradient function;
The maxLik function can't enter gradlik function (definition of gradient function); I guess my mistake is in line ******** ,that the vector ‘h’ is

[PATCH] Fix miscompile of SSE resampler
From: Thorvald Natvig <slicer at users.sourceforge.net>
Some optimizing compilers miscompile the current SSE optimizations when
full optimizations are enabled. By using output value pointer instead of
a return value, we can bypass this misbehaviour.

Segmentation fault with expression on linux
I have a problem, that the plot of mathematical formula sometimes
crashes R on Linux (SuSE 6.2 and 7.0 on a Dual PIII/500 machine with 1GB
RAM). The problem occurs for example in demo("graphics"), i.e. in the
last part were the mathematical symbols are plotted.
There are several circumstances to reproduce this segmentation fault,
but the following is one of the most simple examples. The

Error in cor.default(x1, x2) : missing observations in cov/cor
Hello,
I'm trying to do cor(x1,x2) and I get the following error:
Error in cor.default(x1, x2) : missing observations in cov/cor
A few things:
1. I've used cor() many times and have never encountered this error.
2. length(x1) = length(x2)
3. is.numeric(x1) = is.numeric(x2) = TRUE
4. which(is.na(x1)) = which(is.na(x2)) = integer(0) {the same goes for
is.nan()}

plotting partial deriviatives
Dear R Helpers:
I am trying to annotate a plot. The following code snippet works, but it is
kind of a kludge since it adds the partial derivative symbols after creating
the plotmath frac(). Is there a more elegant way to write a partial
derivative?

Hi,

The offset influences only the start address of the
partition. The alignment goal is about the end address.
So these concepts are nearly independent.
Of course, partition start must be smaller than partition
