Dear R-Core team, Dear Rcpp team and other package teams, Dear R users, The new package 'bit64' is available on CRAN for beta-testing and code-reviewing. Package 'bit64' provides fast serializable S3 atomic 64bit (signed) integers that can be used in vectors, matrices, arrays and data.frames. Methods are available for coercion from and to logicals, integers, doubles, charact...

Dear R community, The new version of package 'bit64' - which extends R with fast 64-bit integers - now has fast (single-threaded) implementations of the most important univariate algorithmic operations (those based on hashing and sorting). Package 'bit64' now has methods for 'match', '%in%', 'duplicated', '...

...would keep working indefinitely. *** 2010 SOLUTION*** There were 2 possibilities at the time: a) Using 64-bit integers. b) Using "double precision integers": Solution Finally Chosen at 2010. Reason: In order that not all R packages using compiled code had to be patched extensively. *** BIT64 PACKAGE*** Nowdays, we have 'bit64' Package, which provides serializable S3 atomic 64bit (signed) integers (+-2^63). But this are not a replacement for 32bit integers, as integer64 are: * Not supported for subscripting. * Have different semantics when combined with double, e.g. integer64...

Thank you Martin for giving to know and developing 'Rmpfr' library for unlimited size integers (GNU C GMP) and arbitrary precision floats (GNU C MPFR): https://cran.r-project.org/package=Rmpfr My question is: In the long term (For R3.7.0 or R3.8.0): Does it have sense that CMP substitutes INTSXP, and MPFR substitutes REALSXP code? With this we would achieve that an integer is always an

Dear R Developers, There is an interesting issue related to "reticulate" R package which discusses how to convert Python's non-32 bit integers to R, which has had quite an exhaustive discussion: https://github.com/rstudio/reticulate/issues/323 Python seems to handle integers differently from R, and is dependant on the system arquitecture: On 32 bit systems uses 32-bit integers,

...uble, so it requires adding an S3 class and overriding every generic function with a custom method. Not all functions are generic, and internal C code will not know about the special class, so this has the danger of code silently interpreting the data incorrectly. This is the approach taken by the bit64 package (and, I believe, the int64 package, but since that's been archived it's not worth considering.

Thank you Gabriel for valuable insights on the 64-bit integers topic. In addition, my statement was wrong, as Python3 seems to have unlimited (and variable) size integers. Here is related CPython Code: https://github.com/python/cpython/blob/master/Objects/longobject.c Division between Int-32 and Int-64 seems to only happen in Python2.

Well I definitely cannot use them as numeric because join is the main reason of those identifiers. About int64 and bit64 packages, it's not a solution, because I am releasing a dataset for external users. I cannot ask them to install a package in order to exploit them. I have to be very carefull when releasing the data. If a user just use read.csv functions, they by default cast the identifiers as numeric. $ mo...

Hello r users, I have to deal with int8 data with R. AFAIK R does only handle int4 with `as.integer` function [1]. I wonder: 1. what is the better approach to handle int8 ? `as.character` ? `as.numeric` ? 2. is there any plan to handle int8 in the future ? As you might know, int4 is to small to deal with earth population right now. Thanks for you ideas, int8 eg: human_id
