My guess is that > class(data[,3])
gives "factor" as the result, try casting to character if so. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Vivek Ayer Sent: Friday, July 24, 2009 1:24 PM To: [email protected] Subject: [R] Colors column don't give correct color with plot() Hey guys, I'm having trouble getting the correct colors, when they are read from a csv file. Here's an example: 1 1 black 1 2 green 1 3 green 1 4 black 1 5 peachpuff Call it blah.csv. Then I ran: data <- read.csv("blah.csv",header=FALSE,sep="") and then to plot the data, I ran: plot(data[,1],data[,2],col=data[,3]) But the output reports a vertical line with colors: black red red black green going up. Is this a bug in R? If so, could someone fix it?
