## identify with mfcol=c(1,2)

 I would like to have a figure with two graphs. This is easily accomplished using mfcol: oldpar <- par(mfcol=c(1,2)) plot(x,y) plot(z,x) par(oldpar) I run into trouble if I try to use identify with the two plots. If, after identifying points on my first graph I hit the ESC key, or hitting stop menu bar of my R session, the system stops the identification process, but fails to give me my second graph. Is there a way to allow for the identification of points when one is plotting to graphs in a single graph window? My code follows. plotter <- function(first,second) {   # Allow for two plots in on graph window.   oldpar<-par(mfcol=c(1,2))     #Bland-Altman plot.   plot((second+first)/2,second-first)   abline(0,0)   # Allow for indentification of extreme values.   BAzap<-identify((second+first)/2,second-first,labels = seq_along(data\$Line))   print(BAzap)   # Plot second as a function of first value.   plot(first,second,main="Limin vs. Limin",xlab="First (cm^2)",ylab="Second (cm^3)")   # Add identity line.   abline(0,1,lty=2,col="red")   # Allow for identification of extreme values.   zap<-identify(first,second,labels = seq_along(data\$Line))   print(zap)   # Add regression line.   fit1<-lm(first~second)   print(summary(fit1))   abline(fit1)   print(summary(fit1)\$sigma)   # reset par to default values.     par(oldpar) } plotter(first,second) Thanks, John John David Sorkin M.D., Ph.D. Chief, Biostatistics and Informatics University of Maryland School of Medicine Division of Gerontology Baltimore VA Medical Center 10 North Greene Street GRECC (BT/18/GR) Baltimore, MD 21201-1524 (Phone) 410-605-7119 (Fax) 410-605-7913 (Please call phone number above prior to faxing) Confidentiality Statement: This email message, including any attachments, is for th...{{dropped:6}} ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.
