fexact.c
Dear All,
I am using fexact.c on a C++ program I wrote. To minimize dependencies on
other files (e.g., to not need to include R.h and ctest.h ---now I only
include the R files Boolean.h, Constants.h, and Memory.h), I have re-written
all declarations of Sints as ints and, what is potentially more serious, I
have re-written the line (lines 329 and 330, in fexact.c on R-1.6.1)

Hello,
I'm using R to apply Fishers exact test to a whole pile of

fisher.test FEXACT error 7
Hello,
I have an error message that doesn't seem to make sense in that having
read the R documentation I was under the impression that R was able to
grab as much memory as it needed, and has been able to do so for some
time, so the advice given below about increasing the size of the
workspace is redundant.
If I'm right, does anyone have a solution to the problem of the size of

fisher.test - FEXACT error 7
Dear all,
I’m having an awkward problem in R. When I write the command
Fisher.test(school.data,workspace=2e+07), where school.data is the matrix
corresponding to the data set,
I get the error message:
FEXACT error 7.
LDSTP is too small for this problem.
Try increasing the size of the workspace.

Dear Help Desk,
Is there any way to change some of the labels on R diagrams?
Specifically in histograms, I would like to:
1. change the word frequency to count.
2. Make the font of the title (Histogram of …) smaller.
3. Have a different word below the histogram than the one occurring in the title (right now if you choose X for your

possum sleeping: thanks and fisher.test() FEXACT error
Dear helplist
Many many thanks to everyone who helped me. The trick was to use
tabulate() or, better,
tab <- rep(0,50)
names(tab) <- 1:50
tab[names(table(sleeps))] <- table(c)
My original dataset was a list of 50 trees and a length 12 vector
recording which tree a certain possum slept in on 12 nights. As
Professor Ripley points out, a Monte-Carlo simulation is easy to set
up, and it

blackboost (mboost package) function leads to non-reclaimable memory usage
Dear all,
I am puzzled by R's memory usage when calling the blackboost function from
package mboost to estimate a Gradient boosting model on a simulated dataset
with 20 correlated variables and 100,000 obs. The blackboost object created
by the function is only 15.3Mb, but R's memory usage increases by about
3.9Gb during the estimation of the model and the memory is not released even
after

fisher.test
Hi!
I am Marta Colombo, student in Mathematical Engineering at "Politecnico di Milano". For my master degree thesis I have to analyze some categorical data. My dataset is composed by 327 individuals and 16 variables. I am using Fisher exact test to test independence on IxJ contingency tables, but I have a problem with one variable.
R gives me this error message:
FEXACT error 7.

Porting R
I am trying to get R 1.0 running on the Mac.
The main target is MacX. Anyone else working on that?
For the recent Macintosh system, I am trying to compile R using MachTen.
The R core compiles and runs without any changes, using the Unix make files.
The libraries give some problems, presumably due to handling of shared
libraries. It seems I am missing something to link. Before I spend my time

Migration from mbox/maildir++ to mdbox
Dear list,

problem with fisher.test
I posted this last night but I think I figured out the problem.
I checked on the underlying equation for the Fisher Exact Test for tables
greater than 2X2. It looks like I have an insane amount of factorials to be
multiplied.
Is that problem? Is it an overflow issue?

hybrid in fisher.test broken?
The hybrid feature in fisher.test looks to me like an excellent way to
analyze my two-way tables. The only problem is that it does not seem
to be implemented. Am I right about this?
An example is pasted below. I note that I get the warning message only
when I shouldn't: for a 2x2 table hybrid seems to be ignored without
warning. In no case does fisher.test seem to be checking Cochran

Basis of fisher.test
I want to ascertain the basis of the table ranking,
i.e. the meaning of "extreme", in Fisher's Exact Test
as implemented in 'fisher.test', when applied to RxC
tables which are larger than 2x2.
One can summarise a strategy for the test as

problems compiling R packages with Linux
Hello out there,
my first try to install a package (e.g. ctest from CRAN) didn't
succeed; looking at the error messages I think it must be a
configuration problem of my machine, but as I'm not very experienced I
would be glad if someone could give me a hint ...
R's version is 0.63.0, my i386-Linux is kernel 2.0.35. I hadn't had
problems to compile R, and R itself seems to work.
