[R] Greek letters on a multi-line plot title

I have an instance where I need to include Greek letters on a plot title that is multiple lines.   I've searched the forums for an approach to do this, but most of the previous posts and replies seem to just address instances of single line examples and problems:, e.g.   https://stat.ethz.ch/p

I am trying to generate a line graph with quarterly time buckets (with nice labels) on the x-axis. The first block of code below will generate the graph with nicely formatted x-axis labels, but the "type=" and "col=" options are not recognized when factors are used for the x-axis. The second bloc

You'll probably want to look at the 'by' function d=data.frame(sex=rep(1:2,50),x=rnorm(100)) d$y=d$x+rnorm(100) head(d) cor(d) by(d[,-1],d['sex'],function(df)cor(df)) You might also want to look at the doBy package -- View this message in context: http://n4.nabble.com/Mutliple-sets-of-data-in-

Hello, I would like to juxtapose two lattice graphs with common X axes such that the X axes line up. I am using plot right now but the edges are not neat and it would be nice if I could just draw 1 X axis and not both of them. Here is my code: upper<-bwplot(SignalUsed~as.fact

Thank you for taking the time to reply Henrique. Although your solution does take away the zeroes and replaces them with NA's (which i prefer), it unfortunately seems to reduce all of the other scores to just '1': > x <- with(do.call(rbind, df.list), tapply(Score, list(Date, Show, Time), > length
