Peter, The error message comes from panel.loess, which is the panel function that draws the Loess smoothing line. It means one of your groups has too few data points or is too clustered in its domain for the Loess smoother to converge. You could - give up on the pretty-looking smoother - increase

Hello, I am fairly new to R am stumped on how to get the xyplot function in the lattice package to produce a scatter plot of count data versus time, such that the count data represent 8 different groups, and the plot produced has 8 unique "smoothed" lines for the different groups. This is the
