Text Mining
Hi everybody,
I am a new R user. Is there any package devoted to "text mining" analysis in
R ?
Thanks

From z to Rho
Hi,
when performing a spearman_test stratified by a given factor in package "coin", how is it possible to obtain the value of Rho, the Spearman correlation coefficient ?
Thanks in advance

Permutation exact test to compare related series
I all,
is there a way with R to perform an exact permutation test to replace the
wilcoxon test to compare paired series and/or to perform pairwise multiple
comparisons for related series after a Friedman test ?
Thanks

Post-Hoc Test for Kruskal-Wallis Rank Sum Test
Hi list,
I would like to know if there is a way in R to execute a post-hoc test
(factor levels comparison, like Tukey for ANOVA) of a non-parametric
analysis of variance (kruskal.test() function object). I was looking for
something like the Dunn Test. I’ve searched the internet but nothing seemed
to define a way to it.
Do You have any suggestion? Other equivalent test maybe!
Thanks in

Problem with approximate null distribution (package: coin)
Hi,
I am trying to make use of "approximate" option to obtain null distribution
through Monte-Carlo resampling, as described in coin library documentation.
Unfortunately, this does not play well with my data -- permutation process
swallows astonishingly large amounts of RAM (4-5Gb) and runs far too long (30
min for B=10). Apparently, this is caused by the size of my dataset (see

Analyzing three-way contingency tables with many zero cells
Hi all,
I am trying to analyze the following data. The first three columns are
categorical variables (colors of three traits for a peripatus species)
and the last column the count of individuals in each three-way
classification. I wish to test if the three traits vary independently or
if they are correlated across individuals, i.e. - this is a basic three
way contingency table question.

Permutation tests using apply function with package coin
I am using "apply" to run exact permutation t-tests by columns
using the coin package. For example:
library(coin)
dat <- matrix(rnorm(7*35),7,35)
fun <- function(x) {
pvalue( independence_test(x~f,
data=data.frame(x, f=factor(c(rep("a",4),rep("b",3)))),
distribution = "exact"))
}
p.vals <- apply(dat, 2, fun)

A naive question about permutation tests in the coin package
Dear R helpers,
I am trying to understand how to use the independence_test function in
the coin package. I think I suffer from a misunderstanding about what
the package does. Either that or I do not understand how to use it
properly. Specifically, I cannot understand if I can test independence
of arbitrary statistics.
Take the following example:
set.seed(10)
d <- data.frame(y = c(rnorm(10,

Permutation Test on Interactions {coin}
Dear List,
I'm interested in performing a permutation test on the interaction between
a binary treatment indicator and a covariate (either continuous or
categorical). I'm interested in the p-value of the interaction effect from
a permutation test, and I'm using the coin package for that purpose.
As I haven't seen any examples like this in the package documentation (or

one sample permutation test using package 'coin'
Using the package ?exactRankTests? one can execute a one-sample permutation test for a hypothesized location parameter of 0 like:
perm.test(rnorm(30,0))
The package ?exactRankTests? seems now to be deprecated in favor of the ?coin? package which as I understand is a superset of ?exactRankTests? in terms of functionality.
The ?coin? package allows one to run a two-sample permutation test using

coin package (conditional inference / permutation): parameter teststat
Dear R-list members,
This is in fact a question about statistics, not directly
about the R software.
The coin package, for conditional inference through permutation
methods, has as it main function the function independence_test.
One of its parameters is teststat, about which the package
documentation says:
teststat: "a character, the type of test statistic to be applied:

New Installs, Same Trouble Loading doBy and coin Packages
I tried Tal's suggestion of deleting the doBy and coin packages and then
reinstalling them from a different mirror. The first install was from the
Harvard mirror and the second was from the Case Western Univ. mirror. The new
packages generate the same errors when I call them using the library() command.
Also, I tried to load these packages using R and its script editor thinking that

Unexpected results using the oneway_test in the coin package

Wilcoxon signed-ranks test using package coin ?

Coin Toss Simulation
I am trying a simple toin coss simulation, of say 200 coin tosses. The idea
is to have a data frame like so:
Experiment# Number_Of_Heads
1 104
2 96
3 101
So I do:
d <-data.frame(exp_num=c(1,2,3)); /* Just 3 experiments to begin with */
d$head_ct <-sum(sample(0:1,200,repl=TRUE));
d;

error using lapply with oneway_test (coin package)
Dear expeRts,
I would like to use a oneway_test (from package coin) to test whether
two groups differ on various variables. The variables are encoded
within a data frame. Unfortunately, I obtained an error, that I don't
understand. Could you please help me ?
Example:
