AFAIK you need to adjust xlim and ylim in first call of plot as the plot
itself is not redrawn but you only add points (or other graphing objects
like lines) to existing plot. If you know what you want to plot you can
use xlim=range(all.values.you.want.to.plot) for automatic adjustment of

I did look at this function but seems that only works with censored (not
truncated) normal distributions.
I know that a straightforward to do it is with fitdistr from MASS package:

The $ is special in TeX/LaTeX as a shortcut for beginning/ending inline math
mode, so if you want an actual $ then you need to escape it so that the
TeX/LaTeX file has \$ in it. This means that in your R code that generates the
file you may need \\$ or in some cases $.
Hope this helps,
Thanks, but unfortunately
\begin{lstlisting}
\\$
\end{lstlisting}
and
\begin{lstlisting}
$
\end{lstlisting}
still generate the same error.

Greg was referring to what to write in R character literals in order to generate
a single \ in the output from R which in turn would be fed into latex or Sweave
and then latex. Google this: special characters in latex

Thanks for clarifying. Yes, \$ works in latex, but not *within* the

Hi,
Again I'm doing logistic regression using lrm from Harrell's Design
package, but on wide matrices (28 observations, 1891 variables) so L2
penalisation is used. I get the following error, although I've tried
different penalties and different tolerances. The X matrix is scaled and
centred.
Check out the 'fancyvrb' latex package - that is quite flexible and I
wouldn't be surprised if it can help you. Make sure to read the docs
(fancyvrb.pdf).

of class, age and sex on the survival.
Cheers.

Sorry Guys, i
'Rterm --help' shows the usage as:
Rterm [options] [ infile] [outfile] [EnvVars]
just in case you didn't understand what the angle brackets meant:
the term [ infile] means read input from 'infile', and
the term [ outfile] means write output to 'outfile'.
Though your code works at the command
This is a python not an R problem.
Use of redirection is handled by a shell, not by the executable (usually:
it could depend on the compiler). The Windows system and popen commands
(and hence R's system()) does not use a shell: POSIX OSes do.
It will be cleaner to use Rscript to run
