Hello, I have a dataset with three numerical variables, and two factor variables, one of which is shown:
> deel1[,1:4] median ucl lcl coupon.period 1 10.894672 NA 14.255623 fixed0-1 5 12.536729 11.658164 13.341038 fixed1-5 9 10.616561 9.979676 11.039264 fixed5-7 13 8.457571 8.048390 8.723679 fixed7-10 17 7.537831 7.274149 7.895592 fixed10-15 21 4.392874 4.279858 4.586663 fixed15more Think of the data as six regression coefficients, with an upper and lower confidence limit. I would like to make a lattice plot, with the factor (fixed0-1,fixed1-5, etc) on the vertical axis, and the median on the horizontal axis. This is simple: xyplot(coupon.period ~ median,data=prepayment, panel=function(x,y,...){ panel.xyplot(x,y) } ) does the trick. Now I want to have a line extending from the dots representing the median, that run from the median to upper/lower confidence limit. How do pass the information of deel1$ucl and deel1$lcl to the panel function, and how do I make segments within the panel function? Thanks for any help, Ruud ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
