win.metafile on linux?
Dear R-help,
Is it possible to use win.metafile() on *nix versions of R?
I tried R 2.1.1 on FreeBSD and R 1.9.0 on redhat with no success. I need
to give some graphs generated in R to my boss so that he can modify them
in Powerpoint to fit he style of his presentation. Recommendations on
other methods are appreciated as well.

[LLVMdev] A Java version of LLVM Core for LLVM IR Analysis: JLLVM
Hi all,
I'm Hao Liu, a 3rd year graduate student of Shanghai Jiao Tong
University in China.
We've build a project named JLLVM, and it's a java version of LLVM Core
for Java developers.
Our motivation is simple: The LLVM project is a great job. But it is
for C++ developers. *It's difficult for Java developers to analysis

Slow code display in R console
Hi
When I copy a block of code to R console, the code would be displayed
line by line very slowly.
I am using R version 2.6.2(2008-2-8). Does anybody know what is the
reason for the slow display? It was not like this when I used earlier
versions.

How to find the root causes of compiler bugs in practice?
Hi, developers,
Recently, I read two papers [1], [2] about finding the root causes of compiler bugs. However, I do not find any information in these paper about how compiler developers find the root causes of compiler bugs in practice. So I am curious whether these techniques are useful in practice. For my experience, the outputs of compilers are always used to isolate the causes of compiler

barplot: different colors for the bar and the strips
Hi,
I am using barplot and would like to know if it is possible to have bars
filled with one color while use a different color for the shading lines.
The following code colors the shading lines, leaving the bars in white:
barplot(1:5, col=c(1:5), density=c(1:5)*5)
while the colors are applied to the bars when density is removed.
barplot(1:5, col=c(1:5))
I did check ?barplot and found the

P-value for F from summary.lm (was RE: (no subject))
[Please use the subject line!]
In the help page for summary.lm, the "Value" section says that the returned
object has a component called "fstatistic", which has the F-statistic and
the associated numerator and denominator degrees of freedom. You can get
the p-value by something like:
fstat <- summary(speciallinearmodel)$fstatistic

Function Fstats and p value
Hello,
I used the function Fstats (in the package strucchange) and would like to
transform the F probability given by Fstats in P value. This transformation
can be made while making a plot, but I need to have the numerical P value
which are ploted... and I can't find out how to do.
Here a is an exemple, to plot the P value.

Kolmogorov-Smirnov: calculate p value given as input the test statistic
Dear all,
I calculate the test statistic for the KS test outside R, and wish to use R
only to calculate the corresponding p-value.
Is there a way for doing this? (as far as I see, ks.test() requires raw
data as input). Alternatively, is there a way to provide the ks.test() the
two CDFs (two samples test) rather than the (x, y) data vectors?
Thanks in advance,

exact values for p-values
Hi there,
If I do an lm, I get p-vlues as
p-value: < 2.2e-16
Suppose am interested in exact value such as
p-value = 1.6e-16 (note = and not <)
How do I go about it?

How to make a figure plotting p-values by range of different adjustment values?
Hi all,
Thank you for taking the time to read my message. I'm trying to make a
figure that plots p-values by a range of different adjustment values.
(Using the **logit** function in package **car**)
My Statistical analyses were conducted on probability estimates ranging
from 0% to 100%. As it's not ideal to run linear models on percentages that
are bounded between 0 and 1, these

dreaded p-val for d^2 of a glm / gam

I really dread to ask that .... much more that I know some discussion about p-values and if they are relevant for regressions were already on the list. I know to get p-val of regression coefficients - this is not a problem. But unfortunately one editor of a journal where i would like to publish some results insists in giving p-values for the squared deviance i get out from different glm and

How to capture t-score and p-values from t.test
When I do t.test on two distributions (see example below), it outputs
numerous data about the t.test.
What I'd like to do is individually capture some of this data and assign
it to other variables.
However, I am unable to find anything in the help section.
In the example below, the t value is -4.0441 and the p-value is 0.006771
