## Graphics question

 Hi I am trying to plot two points (with confidence intervals) on a graph to illustrate the value of a particular quantity after 1 and 2 iterations respectively. I'm doing this by plot(cycle,alpha[2,],main="",ylim=c(-8,-3),cex=2,col="red",pch=19,ylab=e xpression(alpha),xlab="cycle") Etc.. Where > cycle [1] 1 2 > alpha           [,1]      [,2] [1,] -6.227266 -5.762146 [2,] -5.200972 -5.010401 [3,] -4.174677 -4.258655 When I plot this I get the x-axis scale reading 1.0,1.1,1.2,...,2.0 I want to get it to read simply                 1                2 Is there an easy way to do this? ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

 In reply to this post by Bowden, J.M. xaxp=c(1,2,1) will do so, and look also at par(lab=).
