Hi the list,
I am trying to use R forge. I created an account. I put my project on R
forge. I installed TortoiseSVN on my computer (windows).
Then I did not manage to go through all the key process but I see in the
R-Forge Manual that there is another option:

hi ted, philippe, and others---I agree with everything you write about
good coding practice.none of us would be writing x<-3, even when
we want to assign 3. we know better. we would at least use a space,
if not a paren. alas, my suggestion is not so much for you. It is
trying to spare novi

I can claim some responsibility for 3 sets of functions that are in "core R",
well they are in packages, but then so is the plot function, but packages that
are loaded automatically in a default installation of R. My piece of the
responsibility is probably more the blame than credit (the credit

In the mean time you could have student run the following code each time (put
it into .Rprofile or something) until they learn good coding practices:
testfunc <- function(expr, value, ok, visible) {
tmp <- deparse(expr)
if( grepl( '<- *[0-9.]+ *[])&|]', tmp ) ) {

I have two packages, one that does the actual work (SC) and the other
a Tcl/Tk UI (SCUI) that invokes methods within the former. Within the
SCUI's invocation method, I save an object returned from SC, the
results of a long-running method.
Now the object is completely described by the SC package. U
Hi all,
If a package suggests another package in its description, you can
check it at runtime with requires. How do you do check if a package
is available without loading it, if you only want to access one
function in the package namespace.
Thanks,

Well, not really as requires() can give an error, at least until
2.12.0 is out. So you need to wrap it in

I think the explanation of the NAMED field in the R Internals document
is incorrect. In Section 1.1.2, it says:
The named field is set and accessed by the SET_NAMED and NAMED macros,
and take values 0, 1 and 2. R has a `call by value' illusion, so an
assignment like
b <- a

I recently moved a function 'subset.with.warning' into the 'mvbutils' package
(a version not yet on CRAN). When I tried RCMD CHECK, I got this warning:
