See the title.
isin(x, ...) ## Default S3 method: isin(x, y, ordered = FALSE, ...) ## S3 method for class 'data.frame': isin(x, ...)

vectors. |

further arguments to be passed to or from other methods. |
The function will only return TRUE
if every element of y
is present in the vector x
, counting multiplicity. See the examples below. Of ordered = TRUE
, then elements must be in the vector x
in the order specified in y
. Compare this to the behavior of the %in%
function in the base
package.
This is a generic function with a moethod for data frames, which applies isin()
to each row of the data frame, with a vector as a result.
Logical, or a vector of logicals.
