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 closest I can get to the desired plot:
xyplot(masmean ~ mas, data = Pre96CR.masmeans, groups = behavior, type = 'smooth', span = 0.3, lwd =2, xlab = "Minutes After Sunrise", ylab = "Behaviors at Castle" key = simpleKey(levels(Pre96CR.masmeans$behavior), space = 'right')) This code produces a plot, but one level of the grouping factor ('behavior') is always absent from the plot and in the middle of the plot I receive an error message: Error using packet 1 NA/NaN/Inf in foreign function call (arg 1) Otherwise, the plot is exactly what I want with smoothed lines produced for the 7 other levels of "behavior". Thanks in advance for any ideas/suggestions.
