replacing characters in formulae / models
Dear all,
How can I replace text in objects that are of class "formula"?
y="a * x + b"
class(y)="formula"
grep("x",y)
y[1]
Suppose I would like to replace the "x" by "w" in the formula object "y".
How can this be done? Somehow, the methods that can be used in character objects do not work 1:1 in
formula objects...
Many
