r - Twitter app is not getting started -

-

i have written following script extract tweets twitter.

library("twitter") library("roauth") library("rcurl") library("httr") download.file(url="http://curl.haxx.se/ca/cacert.pem",destfile="cacert.pem") ck <- '4qpoqjoibgogp7ju13akxfp2e' cs <- 'ued02vupial3k8nw8foectzj1uftsefqetqjbyxd21ucj0ohjc' ak <- '136316586-xwncmre5uyszigtowtvyr4nh4gfr01adpr5sf5ik' <- 'zsij4lsdc5xkcdyofwkyijknuy8uj71sg1nfaifkzbgc2' requrl<- 'https://api.twitter.com/oauth/request_token' acurl <- 'https://api.twitter.com/oauth/access_token' auurl <- 'https://api.twitter.com/oauth/authorize' cred <- oauthfactory$new(consumerkey=ck,consumersecret=cs,requesturl=requrl,accessurl=acurl,authurl=auurl) cred$handshake(cainfo="cacert.pem") save(cred, file="twitter_authentication.rdata") load("twitter_authentication.rdata") oauth_endpoints("twitter") myapp <- oauth_app("twitter",key=ck,secret=cs) twitter_token <- oauth1.0_token(oauth_endpoints("twitter"), myapp) setup_twitter_oauth(ck,cs) search.string <- "#bahubali" no.of.tweets <- 10 tweets <- searchtwitter(search.string, n=no.of.tweets, lang="en") tweets write.csv(tweets, file='/home/horopter/tweet/csvtweets.csv', row.names=f)

however setup_twitter_oauth(ck,cs) [1] "using browser based authentication" waiting authentication in browser... press esc/ctrl + c abort

and stuck there. website either says 'you not have permissions.' or doesn't open @ all. if don't give callback url, doesn't authenticate, otherwise gets stuck again aforementioned. me out here.

i used tried using same code , authentication token , here code worked me. setup_twitter_oauth requires ck, cs, ak, as arguments.

library("twitter") library("roauth") library("rcurl")  library("httr") download.file(url="http://curl.haxx.se/ca/cacert.pem",destfile="cacert.pem") ck <- '4qpoqjoibgogp7ju13akxfp2e' cs <- 'ued02vupial3k8nw8foectzj1uftsefqetqjbyxd21ucj0ohjc' ak <- '136316586-xwncmre5uyszigtowtvyr4nh4gfr01adpr5sf5ik' <- 'zsij4lsdc5xkcdyofwkyijknuy8uj71sg1nfaifkzbgc2' setup_twitter_oauth(ck,cs, ak, as) search.string <- "#bahubali"

this should setup authentication once have downloaded .pem file. when asks authentication press 1.

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
