r - Work With a Value in a Data Frame by Character -

-

i have data frame column of text formatted nba season such:

year 2014-15 2013-14 2012-13 ... 1999-00

i need reformat second year. small data set, , don't mind manually fixing 1999-00 value, can't figure out how to:

paste(data$year[1:2],data$year[6:7])

to get:

year 2015 2014 2013 ... 2000

i think simplest extract first year , add one:

as.numeric(substr(data$year, 1, 4)) + 1 # [1] 2003 2002 2001 2000 1999

data:

(data <- data.frame(year=c("2002-03", "2001-02", "2000-01", "1999-00", "1998-99"))) #      year # 1 2002-03 # 2 2001-02 # 3 2000-01 # 4 1999-00 # 5 1998-99

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
