sapply64 {TreeTools} | R Documentation |
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 |
FUN |
the function to be applied to each element of |
... |
optional arguments to |
simplify |
logical or character string; should the result be
simplified to a vector, matrix or higher dimensional array if
possible? For |
USE.NAMES |
logical; if |
FUN.LEN |
Integer specifying the length of the output of |
n |
integer: the number of replications. |
expr |
the expression (a language object, usually a call) to evaluate repeatedly. |
