[R] single strip for the same group in dotplot lattice

[P Tennant]

Hi Luigi,

I'm afraid I don't understand your toy data as you've described it, but 
if you really don't have run 2 for target A, and don't have run 1 for 
target B, why not just create another factor that reflects this, and 
plot that?

  my.data$clus2 <- with(my.data, interaction(cluster, target))

  and call: dotplot(value ~ type| clus2, ... )
