vap {dapr} | R Documentation |
Functions that apply expressions to input data objects and return atomic vectors e.g., numeric (double), character, logical.
vap_dbl: Iterate over input and return double(s)
vap_chr: Iterate over input and return character(s)
vap_lgl: Iterate over input and return logical(s)
vap_int: Iterate over input and return integer(s)
vap_dbl(.data, .f, ...) vap_chr(.data, .f, ...) vap_lgl(.data, .f, ...) vap_int(.data, .f, ...)
.data |
Input object–numeric, character, list, data frame, etc.–over which elements will be iterated. If matrix or data frame, each column will be treated as the elements which are to be iterated over. |
.f |
Function to apply to each element of input object. This can be
written as a single function name e.g., |
... |
Other values passed to function call. |
A double vector
A character vector
A logical vector
A integer vector
