Hallo! GENERAL QUESTION: I'm trying to change the tick marks of the x-axis in a grouped data plot (nlme).
CONCRETE EXAMPLE: In the example (see below) I want the x-axis to have tick marks at 0, 6, 12, 18, 24. How can I do this? WHAT I TRIED I tried "normal" methods like axis(...) but this does not work with this plot. And I also tried xlim=c(0,24) but the ticks are unchanged and the plot looks worse (because of no distances to the border of the Panels). EXAMPLE: -- # begin example library(lattice) library(nlme) # create sample data set.seed(123) ID<-rep(1:6, each=4) Time<-rep(c(0,6,12,24), 6) Y<-runif(24) DF<-data.frame(ID, Time, Y) GDF<-groupedData(Y ~ Time | ID, data=DF) plot(GDF,layout=c(3,2), aspect=0.6, xlab="Months") # end example QUESTION: How can I get tick marks at 0, 6, 12, 18, 24 on the x-axis? Any help will be appreciate. Karl. PS: Have a happy new year and keep R running!! ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
