Dear R users, Is it possible to draw an xyplot (example below) without having to build a dataframe? For example: I have some data in matrix-form. Usually, the first column is the x-value, the columns 2 and 3 are y-values. I would then like to plot 2 panels where the first panel draws the second column against the first column and the second panel draws the third column against the first column. It seems "tedious" to construct a dataframe just for the plots.
Cheers, Marius library(lattice) x <- 1:10 y <- cbind(x,-x) # 2-column matrix p <- cbind(rep(1,10),rep(2,10)) # "panel" matrix xyplot(y~x|p) # does not work; can this be fixed (without the use of a dataframe)? ______________________________________________ R-help@r-project.org 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.
