When plotting a reversed time axis with the base graphics system, R fails to label the axes.
Example: times <- c(Sys.time() - 100, Sys.time()) plot(times, 1:2, xlim = times) # correctly labels the x-axis plot(times, 1:2, xlim = rev(times)) # fails to label the x-axis axis.POSIXct(1, times) # still fails to add labels dates <- c(Sys.Date() - 10, Sys.Date()) plot(dates, 1:2, xlim = dates) # correctly labels the x-axis plot(dates, 1:2, xlim = rev(dates)) # fails to label the x-axis axis.Date(1, dates) # still fails to add labels This is clearly due to the variable keep in both axis functions. keep <- z >= range[1L] & z <= range[2L] But if the axis is reversed that should be: keep <- z <= range[1L] & z >= range[2L] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
