In pure R (without other packages) is IMHO simpler to understand (at least if data are so simple: months 1 till 9 with no missing values...). All you need is:
dummybob <- ' month A B Jan 8 4 Feb 7 5 Mar 6 8 Apr 3 7 May 5 1 Jun 6 4 Jul 2 8 Aug 1 2 Sep 4 3 ' bob <- read.table(textConnection(dummybob), head=TRUE, stringsAsFactors = FALSE) plot(0,0,"n",xlim=c(1,9),ylim=c(0,9),xlab="Month",ylab="Value",axes=FALSE) title(main="Bob") lines(1:9,bob$A,lty="solid",col="black") lines(1:9,bob$B,lty="dotted",col="green") axis(1,1:9,bob$month) axis(2) text(1:9,bob$A,"A",pos=3) text(1:9,bob$B,"B",pos=3) box() And then repeat with the other dataset. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
