Hi list, I just got stuck with this one:
In Data I have the sets age (numbers 1 to 99 and NA) and gender (M, F and NA). Then getting some nice plots using ggplot(data, aes(age[na.exclude(gender)])) + geom_histogram( binwidth = 3, aes(y = ..density.. ), fill = "lightblue" ) + facet_grid( gender ~ .) I am trying to get a faceted graph of age distribution excluding the NA data for gender Unfortunately I end up with the error message: Error in data.frame(..., check.names = FALSE) : arguments imply differing number of rows: 206, 219 How do i Wash out NA's in this situation?
