I believe the `splancs' package from CRAN has a bivariate K function.
For error bars you'll probably have to use Monte Carlo methods.

I would use the subset() function. Assuming the data frame has variable
names "Gender" and "Age", you could do:
Y1 <- subset(X, Gender == 1 & Age >= 18 & Age <= 40)
Y2 <- subset(X, Gender == 0 & Age >= 20 & Age <= 30)

It's important to remember that in R functions return whatever happens

I think with the introduction of namespaces in R version 1.7.0 many of
