I noticed that the following code works with 0.8.9 but not with 0.9.0 (same sessionInfo as #559)
foo <- ymd_hms("2012-02-06 15:47:00")
qplot(hour(foo)) + scale_x_datetime(format = "%S:00")
in 0.9.0 I get the error:
Error in continuous_scale(aesthetics, "datetime", identity, breaks = breaks, :
unused argument(s) (format = "%S:00")
in version 0.9.0, the format argument has been replaced by labels.
qplot(hour(foo)) + scale_x_datetime(labels = "%S:00")
So, at most this is a suggestion to maintain backward compatibility. Feel free to close
Yeah, this was a change to make scale_datetime more similar to other scales.
