I wrote my data file as a tab separated text file.
I managed to get R to
rd <- read.table("file.txt", header=TRUE)
About half of my efforts to plot are errors. I found it easier to
attach( rd )
Apparently I need to remember to detach( rd ) when I am done (and
before I exit R).
plotting the rank of referees was
plot( Rank ~ Week, xlab="GameDay", ylab="Rank" )
but, that uses the same symbol for all referees. So it is a bit better
plot( Rank ~ Week, xlab="GameDay", ylab="Rank" pch=c( Referee ) )
pch is "plot character"? and c is a function to "coerce" data types.
So, the first referee in the vector gets character 1, the second gets
character 2, and so on (I believe).
This is slow, but I guess that is learning curves for you. :-)
To get a good I believe I use the svg function to attach to a file,
plot the data, and then unattach the svg "device".
svg( "file.svg" )
plot( ... )
