as.integer64.character: Coerce to integer64

In bit64: A S3 Class for Vectors of 64bit Integers

Coerce to integer64

Description

Methods to coerce from other atomic types to integer64.

Usage

 NA_integer64_
 as.integer64(x, ...)
 ## S3 method for class 'integer64'
as.integer64(x, ...)
 ## S3 method for class 'NULL'
as.integer64(x, ...)
 ## S3 method for class 'character'
as.integer64(x, ...)
 ## S3 method for class 'bitstring'
as.integer64(x, ...)
 ## S3 method for class 'double'
as.integer64(x, keep.names = FALSE, ...)
 ## S3 method for class 'integer'
as.integer64(x, ...)
 ## S3 method for class 'logical'
as.integer64(x, ...)
 ## S3 method for class 'factor'
as.integer64(x, ...)

Arguments

x	an atomic vector
keep.names	FALSE, set to TRUE to keep a names vector
...	further arguments to the NextMethod

Details

as.integer64.character is realized using C function strtoll which does not support scientific notation. Instead of '1e6' use '1000000'. as.integer64.bitstring evaluates characters '0' anbd ' ' as zero-bit, all other one byte characters as one-bit, multi-byte characters are not allowed, strings shorter than 64 characters are treated as if they were left-padded with '0', strings longer than 64 bytes are mapped to NA_INTEGER64 and a warning is emitted.

Value

The other methods return atomic vectors of the expected types
