Twitter Battle

I love to have fun with R and Twitter...there are a lot of cool things that you can do with it...so I just thought of having a small Twitter Battle application...something that will grab the number of followers and lists from two users...apply some crappy algorithms and determine the Twitter importance between those users...using our .RData file that holds the Twitter OAuth info...

Twitter Battle
require("Rook")
library("ROAuth")
library("twitteR")

setwd("C:/Blag/R_Scripts/Important_Scripts")
load("credentials.RData")

Get_Percentages<-function(p_one,p_two,flag){
      if(p_one > p_two){
        if(flag == 0){
          OneFollowPercent<-100
          TwoFollowPercent<-round((p_two * 100) / p_one)
        }else{
          TwoFollowPercent<-100 - (round((p_two * 100) / p_one))
          if(TwoFollowPercent <= 49){
            OneFollowPercent<-50 + TwoFollowPercent
            TwoFollowPercent<-100 - OneFollowPercent
            flag<-0
          }else{
            OneFollowPercent<-50 + TwoFollowPercent
            TwoFollowPercent<-100 - TwoFollowPercent
            TwoFollowPercent<-100 - round((round(TwoFollowPercent * 100) / OneFollowPercent))
            OneFollowPercent<-TwoFollowPercent
            TwoFollowPercent<-100 - OneFollowPercent
            flag<-1
          }
        }
      }
      if(p_one < p_two){
        if(flag == 0){
          OneFollowPercent<-round((p_one * 100) / p_two)
          TwoFollowPercent<-100

          OneFollowPercent<-100 - (round((p_one * 100) / p_two))
          if(OneFollowPercent <= 49){
            TwoFollowPercent<-50 + OneFollowPercent
            OneFollowPercent<-100 - TwoFollowPercent

            flag<-1
          }
        }
      }
      if(p_one == p_two){

When we execute it...we're going to have some interesting results...




Have fun with it -;)
