Hi Aldi, Yet another way to do what you want. 'd' is your data frame. You cannot easily modify the attributes of the lines however...
# just to set up coordinates plot( d$Location, d$otherinfo, type="n") # plot the lines invisible(by(d, d$indicator, function(dd) lines(dd$Location, dd$otherinfo))) ********************************************************************************* *** Please note that my e-mail address has changed to [EMAIL PROTECTED] *** Please update you address books accordingly.

Hi, Is there a smart way in the R graphs to create a line that is broken in intervals based on the indicator given below. following is a small test graph Location,indicator,otherinfo 1.2,1,2.2 2.5,1,2.5 3.7,1,2.3 20.1,2,4.3 22.5,2,5.2 25.0,2,3.4 27.3,2,2.2 35.1,3,3.4 37.0,3,7.2 38.0,3,6.1 40.1,3,5.4 52.9,3,3.3 Right now in the plot the line is continuous, but I would like to have it broken based on the indicator. If the line of the plot reaches the last observation of indicator=1 then the line needs to stop; the next line will start at location 22.5 and continue up top 27.3; the next line goes from 35.1 up to 52.9. > x<-read.table(file='c:\\aldi\\testgraph.csv',sep=',',header=T) > x Location indicator otherinfo 1 1.2 1 2.2 2 2.5 1 2.5 3 3.7 1 2.3 4 20.1 2 4.3 5 22.5 2 5.2 6 25.0 2 3.4 7 27.3 2 2.2 8 35.1 3 3.4 9 37.0 3 7.2 10 38.0 3 6.1 11 40.1 3 5.4 12 52.9 3 3.3 > plot(x$Location,x$indicator,type='l',xlim=c(0,max(x$Location)),ylim=c(0,max(x$indicator,x$otherinfo))) > points(x$Location,x$otherinfo) TIA, Aldi -- ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
