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.
