extending package with function calling an Objective Caml program
Hallo,
we are trying to extend the R package multcompView in agreement with
the author Hans-Peter Piepho. The function multcompLetters implements
so far a heuristic. We would like to add a function that implements
an exact algorithm and returns a provable optimum result. This
algorithm has been implemented in Objective Caml and we would like to
reuse this code. We wrote an R function

Letters group Games-Howell post hoc in R
Hello everybody,
I use the sweetpotato database included in R package:
data(sweetpotato) This dataset contains two variables: yield(continous
variable) and virus(factor variable).
Due to Levene test is significant I cannot assume homogeneity of variances
and I apply Welch test in R instead of one-way ANOVA followed by Tukey
posthoc.
Nevertheless, the problems come from when I apply posthoc

TukeyHSD output
Hi all,
Is there a R-function that orders Tukey results with conveniant letters, similar to the SPSS output (A, AB, ABC, C, etc.) .

two-way categorical anova post-hoc data extraction
Hi list,
I have a question regarding post-hoc extraction of data from a two-way categorical anova.
I have a categorical anova of this form:
width ~ steepness + patchiness (4 steepness levels, 4 patchiness levels)
This simple setup answers if for the widths I collected across different levels of steepness and patchiness significant differences can be found. Is there a way to look at these

(no subject)
I am interested in using "multcompLetters" after running "kruskalmc" but
I'm a newbie and I'm not having luck figuring it out. I can run "kruskalmc" just fine,
but after studying the documentation for "multcompletters" for a long time,
I cannot figure out how to make it work. Any ideas? R input is below

[LLVMdev] Stack roots and function parameters
So I've managed to get my stack crawler working and passing its unit tests -
this is the one I've been working on as an alternative to shadow-stack: it
uses only static constant data structures (no global variables or
thread-local data), which means that it's fully compatible with a
multi-threaded environment.
One question that has arisen, however, is what to do about function

more simplified output from glht object
Hi,
I use glht to make multcomp, using Tukey, from a glm model.
It is possible to get a more simplified output of result? Somethink like
ordering by letters.
Thanks

Java parser for R data file?
Hi everyone,
Has anyone written a parser in Java for either the ASCII or binary format
produced by save()? I need to parse a single large 2D array that is
structured like this:
list(
"32609_1" = c(-9549.39231289146, -9574.07159324482, ... ),
"32610_2" = c(-6369.12526971635, -6403.99620977124, ... ),
"32618_2" = c(-2138.29095689061, -2057.9229403233, ... ),

Compact letter display for interaction effects
Hello,
I am interested in generating a compact letter display for the results
of Tukey HSD tests that contain interaction effects. The 'cld' method in
the 'multcomp' package seems only to work for main effects. Does such a
thing exist already? Thank you for any thoughts,

Loading multiple packages with install.packages()...
If you can get a vector with all the package names (I do not know how to do this) then you could do something like this;
# Function to check and install missing packages
install_if_missing <- function(pkg) {
if (!require(pkg, character.only = TRUE)) {
install.packages(pkg, dependencies = TRUE)
}
library(pkg, character.only = TRUE)
}
# List of required packages.

R and Java
I am calling R from within Java.
But I don't think that I can get any plots written to file from R - inside
Java.
This snippet of code(from a larger piece of code) compiles in Java, but
doesn't do anything!
functions.append("trial<-c(1,3,4,5)\n");
functions.append("dawpdf<-function(filename){\n");

Letter-based representation of pairwise comparisons
Hi!
I have been working several years with R but it's my first public question.
I hope I'll be clear :) .
This question is related to obtaining letter-based representation of
non-parametric pairwise comparisons.
I have a dataframe with this structure (but with quite more rows and cols):
A B C factor
1 2 2 one
2 1 2 one
2 2 3 two
2 3 2 two
1 4 2 three
9 8 1 three
I have no normality,

-----BEGIN PGP SIGNED MESSAGE-----

Hi folks:
Curious question. I've added Rcmdr to my setup (R 4.4.1). I would like
to add all of the plugins. Is there a way to get install.packages() to
gather up everything starting 'rcmdrplugin', or do I have to list each
package individually between the brackets?? ??
Regards...

Displaying "homogeneous groups" in aov post-hoc results ?
Hello dear R-help mailing list,
A friend of mine teaches a regression and experimental design course and
asked me the following question.
She is trying to find a way to display the "homogeneous groups" (after
performing tukey test on an aov object).
here's an example for what she means by "homogeneous groups":
She did one way anova and got these results for tukey test:

concatenating multiple columns from files
R-users,
I want to concatenate columns from different files in a single object.
I'm doing bad. My peace of code is as follow:
rawdata <- list.files("./data")
for (i in rawdata) {
mat[ ] <- read.table(paste(i ,sep=""))
}
At the end of the loop I have just one column. What I'm doing wrong?
Thanks,
Fred

concatenating expressions and standard text
Hi all,
is it possible to concatenate expressions and basic text when for
instance labeling axis of a plot? I would like to see something like the
concatenation of expression(C[0]) and "for case 1" on my x axis.
Obviously a plot(x, y, xlab=paste(expression(C[0])," in case1")) will
not work.
Thank you in advance,

Concatenating data frames in R versus SAS
I am trying to concatenate 2 datasets that don't have exactly the same
column.
In SAS I did: data summary;
set agency prop;
run;
No problem
in R I get error message
summary <-rbind(agency,prop)
Error in match.names(clabs, names(xi)) :
names do not match previous names
But when I use rbin.fill, that overwrites the second file w/ first one.
Is there a way to replicate the sas process

How do I concatenate two lists element-by-element?
