Hi
[R-2.9.0]
I am having difficulty including a LaTeX formula in an Rd
file.
The example given in section 2.7 in 'Parsing Rd files' is:
\deqn{ f(x) = \left\{
\begin{array}{ll}
0 & x<0 \\
1 & x\ge 0
\end{array}
\right. }{non latex}
For me, this gives:
\deqn{ f(x)
Hi,
I just noticed that rpart behaves unexpectecly, when performing
classification learning and specifying a loss matrix.
if the response variable y is a factor and if not all levels of the
factor occur in the observations, rpart exits with an error:

John,
To the best of my knowledge this problem in R.app has been around at
least since the R-2.8 days, but likely much longer. I never use R from
a Terminal, so don't know if it occurs or not outside R.app.
It's not related to Rcmdr and you're observation is indeed one of the
better ways to
The optimizer in gcc 4.2 (but not 4.1) on Linux seems to get this
issue "right" on one of my test machines (a 32-bit Ubuntu box).
4.1 fails on a 64-bit Linux but I don't have a newer gcc on any
64-bit Linux machine I can find.
A cleaner version of the test is:
% cat t.c
#include
