Thanks Dr. Winsemius. Here's the toy data set. Basically pg = var(t^(3))-var(t^(2), gs = var(t^(2))-var(t^(1)) and ps=var(t^(3))-var(t^(1)). The revised code and the data set is as follows:
n<-seq(4:13) pg<-c(-1.241394e-03, -9.738079e-04, -7.158755e-04, -5.343962e-04, -4.088778e-04, -3.202068e-04, -2.558709e-04, -2.079914e-04, -1.715435e-04, -1.432430e-04) gs<-c(0.0022520038, 0.0020060234, 0.0017601434, 0.0015519810, 0.0013810851,0.0012407732, 0.0011245410, 0.0010271681, 0.0009446642, 0.0008740083) ps<-c( 0.0010106098, 0.0010322155, 0.0010442678, 0.0010175848, 0.0009722074,0.0009205665, 0.0008686700, 0.0008191768, 0.0007731207, 0.0007307653) plot(n, pg, type="l",xlab="n",ylab="Differences of the variances",ylim=c(-0.0012,0.0023) ); lines(gs,lty = 2) lines(ps,lty=5) legend(30, 0.0021, expression( c ( var(t^(3))-var(t^(2)), var(t^(2))-var(t^(1))), var("t^(3))-var(t^(1)) ) ), lty=c(1,2,5)). ________________________________ From: David Winsemius <dwinsem...@comcast.net> Cc: r-help@r-project.org Sent: Mon, July 5, 2010 9:43:19 PM Subject: Re: [R] Help in the legend() On Jul 5, 2010, at 8:06 PM, Shant Ch wrote: > Hi R-users, > > I was plotting the differences of the variances of the three estimators- > T^(1), T^(2), T^(3), ofcourse taking two at a time.
