[R] Using auto.key with two variable plots
Rhelpers: Having a problem solving this. I have an xyplot call that looks like this: print(xyplot(temp_species_EAM_Pred_Pop$x+temp_species_NULL_Pred_Pop$x~temp_species_EAM_Pred_Pop$Action,main=current_species, xlab=Action,ylab=Predicted Pop, xlim=c(xmin,xmax),ylim=c(ymin,ymax), auto.key=list(corner=c(1,1 This is just a scatterplot with two response variables sharing the same predictor variable (temp_species_EAM_Pred_Pop$Action). Right now, the key has the words temp_species_EAM_Pred_Pop$x and temp_species_NULL_Pred_Pop$x next to their symbols. I would like to rename these in the key, say EAM and NULL -- using the group= command doesn't work (since these aren't really different groups). What is the right way to rename these variables in the key? Is using auto.key the right approach? Thanks! --j -- Jonathan A.

Thanks! --j Hi Jonathan, A couple pointers that can make things simpler when working with lattice graphics: 1. put your data into 'long format': x, y, group --- the reshape package is good for this. 2. use the formula interface to lattice plotting functions: xyplot(y_var ~ x_var | panel_grouping_var, groups=color_grouping_var, data=your_dataframe, ...)

Did you try setting the text parameter of the auto.key list?
Something like this:
print(xyplot(temp_species_EAM_Pred_Pop$x + temp_species_NULL_Pred_Pop$x
~ temp_species_EAM_Pred_Pop$Action,
main=current_species,
xlab=Action,ylab=Predicted Pop,
xlim=c(xmin,xmax),ylim=c(ymin,ymax),
auto.key=list(text=c('EAM','NULL'), corner=c(1,1
Thanks!
