is.empty

evaluates empty elements in a vector

This function evaluates if an element in a vector is empty the na.empty argument allows for evaluating NA values (TRUE if NA) and all.na returns a TRUE if all elements are NA. The trim argument trims a character string to account for the fact that c(" ") is not empty but, a vector with c("") is empty. Using trim = TRUE will force both to return TRUE

Usage
is.empty(x, all.na = FALSE, na.empty = TRUE, trim = TRUE)
Arguments
x

A vector to evaluate elements

all.na

(FALSE / TRUE) Return a TRUE if all elements are NA

na.empty

(TRUE / FALSE) Return TRUE if element is NA

trim

(TRUE / FALSE) Trim empty strings

Value

A Boolean indicating empty elements in a vector, if all.na = FALSE a TRUE/FALSE value will be returned for each element in the vector
