A common blunder in R programming is to mistype one of a set of filters without realizing. This function will error if any member of the values to be matched against is not present.
lhs %ein% rhs lhs %enotin% rhs
| lhs | Values to be matched |
|---|---|
| rhs | Values to be matched against. |
Same as %in% and %notin%, unless an element of rhs is not present in lhs, in which case, an error.
