Arguments

x,z	Object of class onion
value	replacement value

Value

Extraction and methods return an onion or onionmat. Replacement methods return an object of the same class as x.

Note

If x is a numeric vector and y a onion, one might expect typing x[1] <- y to result in x being a onion. This is impossible, according to John Chambers.
