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
