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.

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().

Examples

sapply64(as.phylo(1:6, 6), as.TreeNumber)
#> integer64
#> [1] 1 2 3 4 5 6
vapply64(as.phylo(1:6, 6), as.TreeNumber, 1)
#> integer64
#> [1] 1 2 3 4 5 6
set.seed(0)
replicate64(6, as.TreeNumber(RandomTree(6)))
#> integer64
#> [1] 90 10 77 30 90 68
