I'm running R 2.11.1 (MacBook Pro and OS X 10.6.4) and am trying to set a line type in the contour() function. What I did was:
> u<-seq(0.005,0.995,0.005) > v<-u > p<-rep(0,length(u)*length(u)) > dim(p)<-c(length(v),length(v)) > for (i in 1:length(u)) for (j in 1:length(v)) p[i,j]<-u[i]^2+v[j]^2 > contour(u,v,p) This produces a nice contour plot, as expected. However, if I execute: > contour(u,v,p,lty=2) I still get a solid line drawn. I also tried: > contour(u,v,p,lty="dashed") with the same result (solid line). Interestingly, if I load the volcano data from the datasets package and run > contour(volcano,lty=2) R draws a nice dashed line for the contours. I tried the usual suspects (Googled plenty) and have not found a solution to my issue. has anyone else encountered this problem? Any clues for me? I don't mind doing the work, but am at a lack for direction. Thanks... -=d P.S. I can attach a graphic if that would help, but thought I'd preserve the bandwidth for this iteration. _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-mac
