I can't believe I'm having such a hard time with this and I haven't been able to find out how to solve this... lab <- expression( paste( hat(v), as.character(round(y.hat,2)), ",", hat(sigma)^2, as.character(sigma.hat)) ) text( x=pt$x+2, y=pt$y,labels=lab ) ## the text should be \hat{y} = <value of y.hat>, \hat{\sigma}^2 == <value of sigma.hat> and R

I've been working on a LaTeX document that contains Sweave code and cannot get MikTeX to find the Sweave.sty file. I've added the c:\rw1081\share\texmf path in the MikTeX roots (I've ven added the path in the environment variables ) but to no avail. Is there a trick to getting Sweave installed correctly when using MikTeX on Windows XP? Do I need to move/copy the Sweave.sty file to the

R gurus: I'm thinking about using R for website traffic analysis but didn't find anything in my web searches specific to R. If I have the webpages (simple example would contain something like three (3) static pages with a couple of links each) and parse the apache access log file (httpd-access.log), then I can populate the graph representing the website and perform whatever analysis I

Hello, Based on reading the Windows FAQ and searching the list archives, I gather that in the past, Active Tcl 8.3.x has been required in order to use the tcltk package under R for Windows.

I am converting some S-PLUS scripts that I use for creating manuscript figures to R so that I can take advantage of the plotmath capabilities. In my S-PLUS scripts I like to use the key() function for adding legends to plots, and I have a couple of questions regarding using the legend() function in R. 1) is there a way to specify different colors for the legend vector of text values? 2) is there

I've figured out how to use optim (barely) to estimate 2 parameter = weibull distributions. I can't get over how easy this is. What I need to = do is use a weight in the observations..... For example,=20 the tree diameters and weights are are=20 4.70 , 100 6.00, 98 7.10, 75.0 8.10, 86.3 8.60, 80.456 8.90, 20.5 9.50, 16.6 11.40, 12.657 11.80, 12.47 14.50,
