[R] xyplot question

[Wayne.W.Jones at shell.com]

The following link is an excellent reference which gives R code for making different plots in R.

Is it something like this you want:

The code can be found to do this on the webpage.

Subject: [R] xyplot question


I am tring to add error bars to data in an xyplot.  Below is the
content of a CSV file that I am trying to use and the code which plots
the data points and 45 degree lines in each of the panes of the
trellice.  I want to add error bars that go up and down to the limits
set by the lcl and ucl values in the data set.  How the heck can I
specify the error bars in a lattice plot?

If anyone knows how to do this can you please tell me how to do it and
more importantly point me toward a book/paper that explains how to do
this and has examples. :~)  As always, help is profoundly appreciated.

fig2 = read.xls("figure2.csv")

library(lattice)
library(grid)

with(fig2,
          xyplot(y ~ x |  group * Method,
          xlab = "",
          xlim = c(-5, 1),
          ylab = "",
          ylim = c(-5, 1),
          col = "black",
          groups = group,
          aspect = 1,
          lx = lcl,
          ux = ucl,
          pch = 16 ,
          panel = function(x, y, ...) {
             panel.superpose(x, y, ...)
             panel.abline(0, 1)

         },
         )
)
