Subject: aggregate and median
Hello R-experts,
I have a simple question: how do I aggregate data using the median
function with na.rm = TRUE, i.e.
aggregate(x, list(x$y, x$z), FUN = '????')
I have tried 'median(x, na.rm = TRUE)' but that doesn't help.
Any suggestions are very much appreciated,
Thorsten
