Hi, I tried to pass the function dist() as an argument, but got an error message. However, almost the same code with mean() as the function to be passed, it works ok.

foo<-function (x,

    xfun = dist)

Error in foo(matrix(1:100, nrow = 5)) : could not find function "xfun"

foo<-function (x,

     xfun = mean)

[1] 5.5

what am I missing here?
