Unexpected behaviour of read.table
When reading comma-delimited files as saved from a spreadsheet (unfortunately
many of my scientific collaborators give me these) in read.table(), missing
values are spotted most of the time. Unfortunately when comma is the first
character on the line it gets it wrong. For example, reading the file

R-beta: R without graphics
Is there a way to "unplug" the windows graphics from
R, so that it will work across a teletype telnet
session or in a Linux box proving resistant to having
windows added to it?
Thanks

Professors Bates and Ripley both pointed out that calloc

Checking the existence of a file
Is there a platform-independent way of checking in R whether a
given file exists in the user's filespace?
(so in a unix system, can you check within R whather, say,
/homef/jonm/thisfile
exists)
Thanks

Intermediate LaTeX output generated by R CMD Rd2dvi
Is there any way of getting just the LaTex output which
R CMD Rd2dvi
generates on the way to produces a .dvi file,
which could then be incoorporated into another

Defining own variance function / quasi-likelihood in a GLM
Hello,
I've been looking in the on-line manuals and searching past posts but
can't find an answer to this question.
I'd like to define my own variance function in a GLM.
The function glm(formula, family=quasi(var="var function"))
lets me choose from a selection of built in variances, but I want to
define my own function for the variance.
Is there an S-plus

Why are looping variables not local?
Hello,
I've had a quick look on the list and can't find an answer to this niggle.
Whilst debugging some code, I noticed that looping variables in R are not
local to the loop as seams common in procedural languages.
For example consider the following piece of code:
for(i in 1:3){
cat(i,"")
for(i in c("a","b","c")){
cat(i,"")

No subject
(I dithered a bit about whether this belongs on r-help
(as part of it is a general R question) or r-devel
(as it's a question relating to putting stuff on
CRAN) but decided it might be of general enough interest
to go on the former )

glm() function not finding the maximum
Hello,
I have found a problem with using the glm function with a gamma
family.
I have a vector of data, assumed to be generated by a gamma distribution.
The parameters of this gamma distribution are estimated in two ways (i)
using the glm() function, (ii) "by hand", using the optim() function.
I find that the -2*likelihood at the maximum found by (i) is substantially
larger than that

R-beta: Logistic regression....
Dear R-users
I am introducing my collegue to R and she is interested
to use R to perform Polytomous Logistic Regression
called also Multi-category logistic regression. Is there
any program in R doing this?
Thank you so much for any feedback.
I take this opportunity to thank people who were kind to answer my
query about how to include a postscript file generated from R, in a

obtaining output from an evaluated expression

I am trying to use the deriv and eval functions to obtain the value of a
