%*% in examples (PR#855)
Hi,
when we add
\examples{
a <- 1:4
a %*% a
}
into a Rd-file are run R CMD check, the resulting R code is
a <- 1:4
a
So, %*% ... is lost on the way if I'm not totally confused.

effect sizes for Wilcoxon tests
Hello,
I use t.test for normal distributed and wilcox.test for non-normal
distributed samples.
It is easy to write a function for t.test that calculates the effect
size, because all parts of the formula are available from the t.test
result: r = sqrt(t*t / (t*t + df))
However, for Wilcoxon tests, the formula for effect sizes is:
r = Z / sqrt(N)
I wonder how I can calculate the Z-score in R for

Permutations
Hi,
this is maybe not a real R problem but I want to solve this in R ;-)
Consider the set of all permutations of 1:N (=: S, say) and a fixed
element a from S. I now need to compute the number of permutations s from
S which are elementwise less or equal to a: | { s \in S | s <= a } |
Of cource, backtracking using a tree structure is possible. Does anyone
know an efficient way?

vectors / matrices
Hi,
a friend of mine came across this
R> x <- 1:5
R> cbind(x,x)
x x
[1,] 1 1
[2,] 2 2
[3,] 3 3
[4,] 4 4
[5,] 5 5
R> rbind(x,x)
[,1] [,2] [,3] [,4] [,5]
x 1 2 3 4 5
x 1 2 3 4 5
x is a vector and therefore has no dim-attribute. Obviously cbind treats x
as a col-vector but rbind treats x as a row-vector, that is: two
functions have a different

multcomp and lme
I suppose that multcomp in R and multicomp in S-Plus are related and it
appears that it is possible to use multicomp with lme in S-Plus given the
following correspondence on s-news

Is it possible to use multicomp with lme in R and if so what is the syntax

Generating 2x2 contingency tables
Hello R-users,
I would like to generate two-way contingency tables with zero in one cell. I tried to use the function r2dtable but I could not force one cell to have zero value.
Any Idea?

F90 in packages
Hi,
did anybody manage to compile F90 sources in an R-package? The major
problem is, at least in my opinion, that non of the "free" F90 -> F77
converters is working correctly, at least for the F90 sources
I need to compile.

cex.axis in boxplot (PR#2628)
Hi,
the graphical parameter "cex.axis" does not have any affect for "boxplot":

The patch is simply adding "cex.axis" to the search for axis relevant
parameters in "bxp":

`var' broken in 1.8.0 alpha (2003-09-15)
Hi,
in last nights alpha version, `var' is broken:
R> var(rnorm(100))
Error in var(rnorm(100)) : 3 arguments passed to "cov" which requires 4.
which I suspect is due to recent changes to `cov'. The same is true for
R> cov(rnorm(100), rnorm(100))
Error in cov(rnorm(100), rnorm(100)) : 3 arguments passed to "cov" which
requires 4.

plot.dendrogram and expressions
Hi,
currently the "label" and "edgetext" attributes of a dendrogram are
coerced to character before they are added to a plot with `text'. Is there
a specific reason to do so (expect for the determination of the size of
the character string to be plotted)? Otherwise one could plot the
attributes directly via
diff dendrogram.R /usr/src/R/src/library/stats/R/dendrogram.R
