I put together this J based on the "fivenum" routine in R mentioned in the
Wikipedia link:
fivenum=: 3 : 0
if. 0=#y=. /:~y do. 5#_.
else. n4=. -:<.-:3+#y
d=. <:1,n4,(-:>:#y),(n4-~>:#y),#y
-:(y{~<.d)+y{~>.d
end.
)
It returns the minimum, the quartile points, and the maximum of a series.
The first branch of the "if" roughly replicates some of the R function's
NA-handling.
