# S3 method for shapviz
+(e1, e2)

# S3 method for mshapviz
+(e1, e2)

Arguments

e1

The first object of class "shapviz".

e2

Value

A new object of class "shapviz".

Examples

S <- matrix(c(1, -1, -1, 1), ncol = 2, dimnames = list(NULL, c("x", "y")))
X <- data.frame(x = c("a", "b"), y = c(100, 10))
s1 <- shapviz(S, X, baseline = 4)[1]
s2 <- shapviz(S, X, baseline = 4)[2]
s <- s1 + s2
