Hello, I'm using R-2.9 and have a question about integer ranges. On C, (OS X platform), LONG_MIN and LONG_MAX(from limits.h) correspond to -2147483648(-2^31) and 2147483647 (2^31-1) In Java(1.4), Integer.MIN_VALUE and Integer.MAX_VALUE have the same values.
On R, as.integer(2^31-1) is the maximum (without returning NA) but the lowest is -2147483647 (-2^31+1) > as.integer((-2)^31) [1] NA So in both Java and C can hold 2^32 different values, but R holds 2^32 -1 different values. Have I made a mistake? Is there a reason for the difference?
