Problem with adding slots to S4 object
Dear all,
I'm trying to create a virtual S4 class with some subclasses. I noticed
that adding slots to this class increases the memory use and slows the
functions down. Note that I'm adding very small slots (integer or character
both of length 1).
I've made a reproducible example at
https://github.com/ThierryO/testvirtualclass. The R CMD check --as-cran
fails on the tests.

by() and CrossTable()
I am attempting to produce crosstabulations between two variables for
subgroups defined by a third factor variable. I'm using by() and
CrossTable() in package gmodels. I get the printing of the tables first
and then a printing of each level of the INDICES. For example:
library(gmodels)
by(warpbreaks, warpbreaks$tension, function(x){CrossTable(x$wool,
x$breaks > 30,

Percentages in contingency tables *warning trivial question*
I hesitate to post this question in the light of recent threads, indeed
I have hesitated for several weeks, however I have come to a full stop
and really need some help if I am going to progress. I am a new user of
R for medical statistics. I have attempted to read all the relevant
documents, but would welcome any suggestions as to what I have missed.

read.table performance
** Disclaimer: I'm looking for general suggestions **
I'm sorry, but can't send out the file I'm using, so there is no
reproducible example.
I'm using read.table and it's taking over 30 seconds to read a tiny file.
The strange thing is that it takes roughly the same amount of time if the
file is 100 times larger.
After re-reviewing the data Import / Export manual I think

question on simple graph
I am having trouble generating a graph.
I want to know the % of respondents who answered that they "strongly
agree" or "agree" the "America owes R's ethnic group a better chance"
(BTTRCHNC) and I want to organize it by racial group (RACESHRT).
"BTTRCHNC" is organized ordinally from 1 through 5 with 1=Strongly

Good evening R-users!
I have the following problem: i want to get a weighted crosstable along with the adjusted standardized residuals test
Example:

testing correlated proportions
A question about comparing symptom reduction over time and across
treatment groups. Each respondent is asked twice if they
experience symptoms (coded 1), at baseline and then at 6 months
later. They are randomly assigned to either the control or the
intervention group. The 2x2x2 table below shows the frequency
counts.
As can be seen in the margins of the table, 21% of the control

line profiling
Hello,
This is about the new "line profiling" feature in R 3.0.0. As I was
testing it, I find the results somewhat disappointing so I'd like to
get your opinion.
I put some poorly written code in a test.R file, here are the contents:
double <- function(x) {
out <- c()
for (i in x) {
out <- c(out, 2*i) # line 4
}
return(out)
}
Then this how I source the file

Bug in gmodels CrossTable()?
Is the code below showing a bug in Crosstable()? My expectation was that
the values produced by xtabs were rounded instead of truncated:
library(gmodels)
abc <- c("a", "a", "b", "b", "c", "c")
def <- c("d", "e", "f", "f", "d", "e")
wgt <- c(0.8, 0.6, 0.4, 0.5, 1.4, 1.3)

Problem with adding slots to S4 object
There are too many arguments in the signature of the my_inla generic. The
signature defaults to every argument in the formals, which are probably
already over-specified. Typically, one defines a generic with the formals
(x, ...), or perhaps in this case (x, model, ...), but more on that below
Unrelated to this issue, the my_inla generic is defined incorrectly. It

Cross Tables with odfTable in odfweave
Hi, I've been trying to prepare some crosstables for some survey
questions for a client. I have been using the CrossTable function in the
gmodels package. However, this command only seems to be able to create
CrossTables in text documents.
I've been trying to use odfTable in odfweave to create tables that are
standalone objects in the document that I can then convert to other

Question On CrossTable function in gmodels package

I have the following problem with CrossTable function within ?gmodels? package: the output of the function (format ?spss? and asresid=T) can not be stored within another object.

Basically the output consist of self.time and total.time. I have the

Is there a bug in CrossTable (gmodels)
Library gmodels include a function CrossTable that is useful for
crosstabulation. In the help, it is indicated that one can call this
function as CrossTable(data), were data is a matrix. However, when I try
to use this option, it doesn't help. Any idea? Is there a bug?
Thanks for your help.

wish list: generalized apply
Dear All,
I regularly want to "apply" some function to an array in a way that the arguments to the user function depend on the index on which the apply is working. A simple example is:
A <- array( runif(160), dim=c(5,4,8) )
x <- matrix( runif(32), nrow=4, ncol=8 )
b <- runif(8)
f1 <- function( A, x, b ) { sum( A %*% x ) + b }
result <- rep(0.0,8)

Proportions again
Hello.
I asked before and it was great, cause as a beginner I learned a lot. But, if I have this in R (1 and 2 are codes for sex):
> sex<-c(1,2,2,1,1,2,2,2)
> sex
[1] 1 2 2 1 1 2 2 2
I´d like to obtain the proportion according to sex.So I type:
> prop.table(sex)
[1] 0.07692308 0.15384615 0.15384615 0.07692308 0.07692308 0.15384615 0.15384615

The result is OK, but I
