Good... this function, originally named print.coefmat(),
is 25 years old (in R) now:

format.pval () and printCoefmat ()
Hi List,
My goal is to force R not to print in scientific notation in the sixth column (rel_diff - for the p-value) of my data frame (not a matrix).
I have used the format.pval () and printCoefmat () functions on the data frame. The R script is appended below.
This issue is that use of the format.pval () and printCoefmat () functions on the data frame gives me the desired results, but coerces

printCoefmat(signif.legend =FALSE) (PR#7802)
printCoefmat(signif.legend =FALSE) does not work properly. The option
"signif.legend = FALSE" is ignored as shown in the example below.
cmat <- cbind(rnorm(3, 10), sqrt(rchisq(3, 12)))
cmat <- cbind(cmat, cmat[,1]/cmat[,2])
cmat <- cbind(cmat, 2*pnorm(-cmat[,3]))
colnames(cmat) <- c("Estimate", "Std.Err", "Z value", "Pr(>z)")

Dramatic slowdown of R 2.7.2?
Dear R users/developers,
simple comparison of code execution time of R 2.7.1 and R 2.7.2 shows a
dramatic slowdown of the newer version. Rprof() identifies .Call
function as a main cause (see the code below). What happened with R
2.7.2?
Kind regards

printCoefmat with more p-values?
Dear useRs,
I would like to summarize results of several tests in groups of two
columns - statistic, p-value, statistic, p-value etc. There would be
nice to add significance stars, but printCoefmat allows to do it only to
last column. Is there any way to do format such table without writing my
own complicated function?
Thank you in advance,

The argument 'eps.Pvalue' of `printCoefmat()`
Hi all,
Just a minor issue that I am not sure whether this is considered a
"bug." It is about the help page.
In the help page of printCoefmat(), for the argument 'eps.Pvalue', the
description is as below:
number, ..
I have to read the source to figure out that this argument is to be
used by format.pval().
Maybe the description of 'eps.Pvalue' can be revised to refer

printCoefmat() for a data.frame with factors
I want to use something like printCoefmat() in a print.summary method to
print a more nicely formatted version
of the result from a summary method, but where the estimates may be
cross-classified by one or more factors.
However, printCoefmat() assumes that the labels for the parameters are
the rownames of the object, and
prints factors as integers. With one factor, I could just assign that as

printing coefficients with text
I want to print the coefficient estimates of a model in a way
as consistent with other output in R as possible. stats provides the
printCoefmat function for doing this, but there is one problem. I
have an additional piece of textual information I want to put on the
line with the other info on each coefficient.
The documentation for printCoefmat says the first argument must be
numeric, which

understanding print.summary.lm and perhaps print/show in general
I'm trying to understand how R prints summary.lm objects and
trying to change it slightly for a summary function that
calculates standard errors using an alternative method.
I've found that I can modify a summary.lm object and then it
prints the modified way but I want to change a few things in
the print method that I think I might just be able to do. One
is that I want the coefficients

How to change the significant codes default?
Dear R experts,
I am posting this question on behalf of a Japanese R user
who wants to know how to change the siginificant codes default.
As you know, R's default significant codes are:
Signif. codes: 0 `***' 0.001 `**' 0.01 `*' 0.05 `.' 0.1 ` ' 1
But he says that it is usual in economics to give codes such as
`***' for 0.01, `**' for 0.05 and `*' for

pairs(), expression in label and color in text.panel
Hello,
I'd like to add custom labels to my pair() plot. These
labels include math expression but they aren't correctly
displayed...
Further, I want that the boxes for the text.panel (diagonal)
have an other background color (grey80). Is that generally
possible? If yes how do I have to set it?
What I've so far is:

Postscript function Bug at R x64 2.12.1?
Hi list. I was saving my modified pairs graphic using a custom panel from
the R Graphics site, and I got an interesting difference in the final image
when I save it as eps or png.
This custom panel make possible to show at the left side of the pairs plot
the p-value as symbol and the correlation r value with its cex proportional
to the r value itself.
Well, when saving as a png file

Plotting survival curves after multiple imputation
I am working with some survival data with missing values.
I am using the mice package to do multiple imputation.
I have found code in this thread which handles pooling of the MI results:

Now I would like to plot a survival curve using the pooled results.
Here is a reproducible example:

Add Significance Codes to Data Frame
I was hoping that there might be some way to attach significance code like
the ones from summary.lm to a dataframe. Anyone know how to do something
like that. Here is the function i'd like to add that functionality to:

I don't see where the significance codes are assigned during summary.glm.
