[R] Unwanted boxes in legend

[Steve Murray]

Dear all,

Thanks for the response, however I'm getting the following error message when I execute the legend command using the 'border' argument:

Error in legend(10, par("usr")[4], c("A", "B",  : 
  unused argument(s) (border = FALSE)


Is anyone aware of any alternative means of switching off boxes around all but one of the elements in a legend?

Many thanks for any input,

Steve
