sapply64: 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.
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.
