1. Please cc anything but personal remarks to the list, not to me.
That will assure better answers.
2. Your query is too vague for me to be sure -- a small reproducible
example of what you'd like would be very helpful here -- but I am
guessing that you want the ?ave function instead of by().

Well, I finally found a roundabout
fun <- function(x, y) sum(x)/max(y)
aggregate(vsid$lev, list(vsid$month, vsid$year), fun, y=by(vsid$date,
vsid$month, function(x) length(unique(x
Thanks,

Thanks Petr for your kind answer. I got it now but it seems that
argument y will not be split by "list(vsid$month, vsid$year)" in the
aggregate function. I should get number of days in each month in the
denominator with "length(unique(y))" but instead I get sum of days in
months in the denominator.

Thanks Petr,
Yes, your code seems to work. But when I try to reproduce it with my
original data set
fun <- function(x, y) sum(x)/length(unique(y))
aggregate(vsid$lev, list(vsid$month, vsid$yeari), fun, vsid$lev=vsid$date)
I get

Hi R-users,
Suppose I have a following data set.
y1 <- rnorm(20) + 6.8
y2 <- rnorm(20) + (1:20*1.7 + 1)
y3 <- rnorm(20) + (1:20*6.7 + 3.7)
y <- c(y1,y2,y3)
var1 <- rep(1:5,12)
z <- rep(1:6,10)
f <- gl(3,20, labels=paste("lev", 1:3, sep=""))
d <- data.frame(var1=var1, z=z,y=y, f=f)
