[R] Lattice barchart legend with panel.barchart

I have constructed a barchart that requires a panel call, but the panel reduces the facsimiles of bars in the legend to small colored circles. You can see this behavior in the following example: Titan <- as.data.frame(Titanic) titanpanel <- function(x,y,...){ panel.barchart(x,y,...) }

[R] function that calculates using preceding records

Greetings: My dataframe has 4 variables: treecode, year, rw (tree ring width), and d (tree diameter). The d variable only has data for 2014. I wish to calculate earlier diameters by subtracting each year's growth (rw) from the previous year's diameter, by treecode. Can anyone help me with
