Visité a CRAN para ver lo que hay de noticias en R-devel. Algo que puede ser de interes para gente com mucho datos puede ser: LONG VECTORS: o There are the beginnings of support for vectors longer than 2^31 - 1 elements on 64-bit platforms. This applies to raw, logical, integer, double, complex and character vectors, as well as lists. (Elements of character vectors remain limited to 2^31 - 1 bytes.) All aspects are currently experimental. Kjetil -- "If you want a picture of the future - imagine a boot stamping on the human face - forever." George Orwell (1984) [[alternative HTML version deleted]]
