For example: I have >data id x y

I started with R and options(width=n), but this does not seem to do anything (in the context of a document -- line command works just fine). I have beating my head against different Lyx document settings without anything to

quota calculating
Hey everyone, Currently where I work we use qmail. Every time a message is delivered, qmail seems to walk through the user''s entire maildir in order to calculate quota usage. Delivering messages simultaneously to just a few users who are allowed large maildirs (1-2GB) will bring our servers to their knees. Which brings me to dovecot. I use dovecot whereever I can, but

cbind error with check.names
Here is an example where cbind fails with an error when check.names=TRUE is set. data(airquality) airQualityBind =cbind(airquality,airquality,check.names =TRUE)  I understand that cbind is a call to data.frame and the following works: airQualityBind =data.frame(airquality,airquality,check.names =TRUE) but I would like to understand why cbind throws an error. I asked this question on SO here:

Adding 95% contours around scatterplot points with ggplot2
Hi all, I have been looking for means of add a contour around some points in a scatterplot as a means of representing the center of density for of the data. I''m imagining something like a 95% confidence estimate drawn around the data. So far I have found some code for drawing polygons around the data. These look nice, but in some cases the polygons are strongly influenced by outlying
