Apply a function that returns 64-bit integers over a list or vector

Description

Wrappers for members of the lapply() family intended for use when a function FUN returns a vector of integer64 objects. vapply(), sapply() or replicate() drop the integer64 class, resulting in a vector of numerics that require conversion back to 64-bit integers. These functions restore the missing class attribute.

Usage

sapply64(X, FUN, ..., simplify = TRUE, USE.NAMES = TRUE)

vapply64(X, FUN, FUN.LEN = 1, ...)

replicate64(n, expr, simplify = "array")

Arguments

X	a vector (atomic or list) or an expression object. Other objects (including classed objects) will be coerced by base::as.list.
FUN	the function to be applied to each element of X: see ‘Details’. In the case of functions like +, %*%, the function name must be backquoted or quoted.
...	optional arguments to FUN.
simplify	logical or character string; should the result be simplified to a vector, matrix or higher dimensional array if possible? For sapply it must be named and not abbreviated. The default value, TRUE, returns a vector or matrix if appropriate, whereas if simplify = "array" the result may be an array of “rank” (=length(dim(.))) one higher than the result of FUN(X[[i]]).
USE.NAMES	logical; if TRUE and if X is character, use X as names for the result unless it had names already. Since this argument follows ... its name cannot be abbreviated.
FUN.LEN	Integer specifying the length of the output of FUN.
n	integer: the number of replications.
expr	the expression (a language object, usually a call) to evaluate repeatedly.

Details

For details of the underlying functions, see base::lapply().
