Details

A character string is converted into a hashcode following Java conventions by s[1]*31^(n-1) + s[2]*31^(n-2) + ... + s[n] using integer arithmetic, where s[i] is the i:th character of the string, n is the length of the string. The hash value of the empty string is zero.

For all other types, as.integer() is called by default.
