Re: [R] Sweave
Thanks Karen and Abhijit.
I have read the section 4.1.2 of the Sweave user manual. Actually the manual
lacks example code.
I would like to change the option in includegraphics, not to change the
true sizes of the pictures.
This is what I usually do :
\begin{figure}
\centering
echo=false,fig=true=
print( acfplot( x ) )
@
\end{figure}
Should I write :
\begin{figure}
\setkeys{Gin}{width=0.7\textwidth}
\centering
echo=false,fig=true=
print( acfplot( x ) )
@
\end{figure}
?
Thanks for your help,
Randall

Dear Randall
I do it like this:
\begin{center}
\setkeys{Gin}{width=0.7\textwidth}
\begin{Scode}{fig=T, echo=F}
...
\end{Scode}
\end{center}
Hope this helps.

Re: [R] Sweave
I am sorry, I don't get it :-(
What's the main body of the Sweave file ?
Randall
2010/8/18 Abhijit Dasgupta adasgu...@araastat.com
No, the \setkeys statement should be in the main body of the Sweave file,
not in the R code part.

Check out FAQ 7.22. You need to use
print(xyplot(mcmc(x)))
since inside an Sweave evaluation, you are not at the command line and it
does not print by default.

Hi Randall,
Sounds like you need to make friends with the str() function, and
perhaps read the documentation about data types in R. For your
particular problem:
library(coda)
m1- matrix(runif(100), nrow=10)
m1.sum- summary(mcmc(m1))
str(m1.sum)
library(xtable)

[R] counting the number of ones in a vector
Dear R users, I want to count the number of ones in a vector x. That's what I did : length( x[x==1] ) Is that a good solution ?

Since I am not too good at programming, the list solution seems the better
one for me. It is also the one advocated by Kevin Murphy.
So rather than writing return(x,y,z), I should write at the end of my
function :
return(list(x=x,y=y,z=z)) is the preferred replacement.
(As the help page for return() has long said.)
g=function() {
#...
result=list(x,y,z)
return(result)
}
Is that correct ?
Then shoud l use g[1] or g[[1]] ?
No change is needed (I think you mean g()$x etc) as return(x,y,z) and
return(list(x=x,y=y,z=z)) are identical in their effects.
Thank you for you help.
Randall
