Hi, I thought that the following code would give me a set of parallel lines on a plot as in the second example.
q<-c(-2253,-2119,-1985,-1850) p<-c(1,2,3,4) a<-rep(min(p),4) b<-rep(max(p),4) plot(p,q) # example 1 lines(c(a,b),c(q,q)) Now this gives me the lines I really want: # example 2 lines(c(a[1],b[1]),c(q[1],q[1])) lines(c(a[2],b[2]),c(q[2],q[2])) lines(c(a[3],b[3]),c(q[3],q[3])) lines(c(a[4],b[4]),c(q[4],q[4])) I assumed that example 1 was a shorter (vectorized) way of writing example 2?? What have I got wrong? cheers, Mikkel ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
