y <- c(15, 32, 47, 61)
plot(x, y, xlab="Date", ylab="Count")
Warns "parameter "ylab" couldn't be set in high-level plot() function",
but generates the label as specified.
Without 'ylab="Count"' no warning message is issued.

Not really a bug. It's a warning message, not an error, and the result is as expected. The underlying problem has been discussed (at least mentioned) several times - and I don't know an _optimal_ solution. The warning comes from axis.POSIXct(1, x, ...) within plot.POSIXct(), because axis() doesn't understand "ylab" which is passed by the ... argument. Uwe Ligges
