The below is the code whuch I tried ,but its not working.Please help.
Playerwnorloss=ifelse(Dataset$Team1==Dataset$winner | is.na(Dataset$Team2==Dataset$winner),"WinningTeam","LossingTeam")

Answer 1

What about:

Dataset$WinningLosing <- ifelse(Dataset$Result == Dataset$Team1 & !is.na(Dataset$Team1) | Dataset$Result == Dataset$Team2 & !is.na(Dataset$Team2), "Winning","Losing")

Output:

       Team1     Team2    Result WinningLosing
1:  Pakistan      <NA> Australia        Losing
2: Australia Australia Australia       Winning
3: Australia      <NA> Australia       Winning

Answer 2

Try this (assume your data is in df):

library(tidyverse)
df %>% mutate(status = ifelse(Result == Team1 | Result == Team2, 'winning', 'loosing'))
