Hello, This is what "Writing R extensions" currently says about R_atof and R_strtod: >> Function: void R_atof (const char* str) >> Function: void R_strtod (const char* str, char ** end) >> >> Implementations of the C99/POSIX functions atof and strtod which >> guarantee platform-dependent behaviour, including always using the >> period as the decimal

Hi all, I have noticed incorrect parsing of very small hexadecimal numbers like "0x1.00000000d0000p-987". Such a hexadecimal representation can can be produced by sprintf() using the %a flag. The return value is incorrectly reported as 0 when coercing these numbers to double using as.double()/as.numeric(), as illustrated in the three examples below:

Hum... This boils down to > as.numeric("1.23e") [1] 1.23 > as.numeric("1.23e-") [1] 1.23 > as.numeric("1.23e+") [1] 1.23 which in turn comes from this code in src/main/util.c (function R_strtod) if (*p == 'e' || *p == 'E') { int expsign = 1; switch(*++p) { case '-': expsign = -1; case

I am trying to build R with 64bit support so I can access more than 2GB of memory on an IBM running AIX. (IBM NightHawk II RS/6000 node with 16 64-bit, 375-MHz POWER3 CPUs and 32 GB of memory, if you want specifics) The 32bit install required little tweaking, but the 64 bit is sufficiently complicated that I thought I would report my findings here and ask for help with the latest (and hopefully

Dear R-developers, I came to a somewhat unexpected behaviour of read.csv() which is trivial but worthwhile to note -- my data involves a protein named "1433E" but to save space I drop the quote so it becomes, Gene,SNP,prot,log10p YWHAE,13:62129097_C_T,1433E,7.35 YWHAE,4:72617557_T_TA,1433E,7.73 Both read.cv() and readr::read_csv() consider prot(ein) name as (possibly confused by
