This implies to use colnames(x) to get the column names of the SHAP and feature
matrix (and optional SHAP interaction values).
# S3 method for class 'shapviz'
dimnames(x)
Arguments
- x
An object of class "shapviz".
Value
Dimnames of the SHAP matrix.
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))
x <- shapviz(S, X, baseline = 4)
dimnames(x)
#> [[1]]
#> NULL
#>
#> [[2]]
#> [1] "x" "y"
#>
colnames(x)
#> [1] "x" "y"
