I've set minimum <- 0 maximum <- 1 The error persists. But besides that, passing 'type="n"' to plot would only make sense when called once an I know there are only NAs to plot. Since I want to generate many charts in a loop I would have to check for plotable data first to decide if 'type="n"' should be passed. As a workaround for now I do something similar. I check if the range to be plotted is completely NA. If so I manipulate one of those observations (which can only be 0, 1 or NA) to an "illegal" value of 0.5.
