I'm using R-2.3.1 but the code in question is the same in the
01-Oct-2006 snapshot for release 2.4.0. I'd like to evaluate an
expression, catching errors and handling them as warnings. My first
attempt:
x <- tryCatch(lm(xyzzy), error=warning)
didn't work; the error is still treated as an err
Hi. Far from complete, but some sketches on a solution is in the
Rdoc-to-Rd translator of the R.oo package. I, the author, never made
this very public because it uses a very ugly parser etc for it, but
the basics is there and I use it to generate \usage{} statements and
class hierarchies automati

I've been looking at documenting S4 classes and methods, though I have a
feeling many of these issues apply to S3 as well.
My impression is that the documentation system requires or recommends
creating basically the same information in several places. I'd like to
explain that, see if I'm correct,
The convention for documenting S4 methods provides a general way to get
the documentation for a method, given the name of the function and the
name(s) of the classes in the signature:
method?"FUN,CLASS1,CLASS2,..."
where FUN is the name of the function and CLASS1, etc. are the names of

Hello,
If repeated calls are made to save() using the same pre-opened gzfile
connection to a file, and then the connection is closed, the objects
saved by the second and subsequent calls are not correctly restored by
repeated calls to load() with a new gzfile connection to the same file.

First, RODBC is indeed quite useful under Linux and I use it to connect
to an Oracle 10g server running on RHEL. Oracle provides FREE Linux
ODBC drivers that support this functionality:

The traditional way to handle something like this is to develop
your own package for R, possibly even consisting of this one example
with your documentation using the standard R documentation protocol.
Instructions for how to do this are contained in the "Writing R

Dear Vittorio,
Thanks for the clarification. This raises two questions: (1) If a *nix
system has an ODBC driver, can one then read Excel, Access, and dBase data
sets via RODBC (which is what the Rcmdr menu item in question provides for)?
(2) If so, is there a way for me to detect whether unixODBC

Dear all,
given two numeric vectors x and y, the ACF(x) at lag k is
cor(x(t),x(t+k)) while the CCF(x,y) at lag k is cor(x(t),y(t-k)). See
below for a simple example.

Thank you, Robin (and Kjetil),
for spotting and reporting this so precisely.
This is a (somewhat rare) example of a bug that is trivial
enough to fix so the fix even made it into the "deep frozen"
release candidate (R 2.4.0, to be released tomorrow).

Is this a self compiled version? The cygwin platform is not supported.
