Dear all, meanwhile i found out how to handle the coordinate thing and plot the lines like i like. the remaining problem is, i need something like names.arg does in barplot for my plot.
my plot connects several dots with several lines. and now i like characters as the names of the intersects of the x-axis. vector1=c(a,b) vector2=c(c,d) # this vector makes sure the yellow line starts at x=2 x=c(2,3) plot(vector,type="b",col="blue",xlim=c(1,4),ylim=c(20,150)) lines(x,fc,col="yellow") does anybody know how to label the x-axis 1st quarter 2nd quarter 3rd quarter and 4th quarter instead of 1.0 1.5 2.0 2.5 and so on ?? thx in advance ! matthias [[alternative HTML version deleted]] ______________________________________________ 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.
