hashCode.String: Returns a hash code for this string
In HenrikBengtsson/R.lang: [R] Class Library - Basic classes

Description Usage Value Author(s) Examples

Returns a hash code for this string. The hashcode for a String object is computed as

s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]

using int arithmetic, where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation. (The hash value of the empty string is zero.)

   s2 <- String("Hello world!")
   hashCode(s1)              # -52967168
   hashCode(s2)              # -52967168
   hashCode("Hello world!")  # -52967168
