Hello R-users I was puzzled by some strange results of an analysis and I found out what is for me a strange behaviour (I won't dare to say a bug) in both plot and points (and I suspect lines and other kind of lower level plots). If you try the following code: > data<-data.frame(dummy1=c(1:10),dummy2=c(1:10)) > plot(data$dummy1,data$dummy3) A plot of the values of dummy1 against

I''m trying to understand the ''Big Picture'' of how Ruby on Rails applications are deployed and operate in distributed environment (one deployment server, many remote servers).

I added :accesskey=>"D" to the html options hash of my link_to tag but nothing happened. Should I keep trying or is this not an option yet? bruce
