Extract or replace the diagonal of a matrix, or construct a diagonal matrix.
Usage
diag(x, ...)
# Default S3 method
diag(x = 1, nrow, ncol, names, ...)
# S3 method for class 'tbl_ddf'
diag(x, axes, ...)
# S3 method for class 'ddf_col'
diag(x, axes, ...)
diag(x, ...) <- value
# Default S3 method
diag(x, ...) <- value
# S3 method for class 'tbl_ddf'
diag(x, ...) <- value
# S3 method for class 'ddf_col'
diag(x, ...) <- valueArguments
- x
A dibble, matrix, vector or 1D array, or missing.
- ...
Unused, for extensibility.
- nrow, ncol
Optional dimensions for the result when x is not a matrix.
- names
(When x is a matrix) logical indicating if the resulting vector, the diagonal of x, should inherit names from dimnames(x) if available.
- axes
A character vector of axes.
- value
Replacement values.
Value
A dibble if x is a dibble. See base::diag() for the return values
of the default methods.
