[R] LaTeX in R
Dear Rers, I understand that I can include R-code in LaTeX using Sweave. Is there a way to do it the other way round? Particularly, I need some TeX symbols in the legend of an R-plot. This can be done in matlab easily, so I am optimistic with R. Any suggestions for a command or package?

Re: [R] LaTeX in R
Thank you, uwe and jeremy. I was actually looking exactly for that! But something still doesn't work: I want to plot a symbol in a legend of a plot, lets say "\sigma = 2". 2 should be the value of a variable. So, when I try mySigma=2;plot(1:10,dnorm(1:10,sd=mySigma),type='l') legend(x="topright",legend=paste(expression(sigma)," = ",mySigma),lty=1) , the sigma is not plotted as a symbol. This version: mySigma=2;plot(1:10,dnorm(1:10,sd=mySigma),type='l') legend(x="topright",legend=expression(paste(sigma," = ",mySigma)),lty=1) gives me a 'real' sigma but the mySigma variable is not evaluated. Any ideas?

Re: [R] LaTeX in R
I finally got everything plotted as I had planned. So, thank you again. Sundars suggestion looks more flexible when it comes to large numbers of categories (i.e. sigmas). In the plot I will be using, there are 3 sigmas... I am keen to learn about that bquote and substitute stuff. I will definitely take a look at your newsletter contribution, uwe. The ';'s were intended to ease the mail2console copy-and-paste, as some mail programs take control of your linebreaks.
