Trying to find row associated with max value in dataframe R

Question

Like the title says. I am having trouble. for example I have a 2 column (V1,V2) dataframe with lots of rows, around 300,000. I know that

max(df$V2) 


        

Answer 1

You have to write

df[which.max(df$V2), ]

If more than one row contains the max:

i <- max(df$V2) 
df[which(df$V2 == i), ]
