To Generate Row number to the dataframe in R we will be using seq.int() function. Seq.int() function along with nrow() is used to generate row number to the dataframe in R.
Let’s first create the dataframe
df1 = data.frame(State = c('Arizona AZ','Georgia GG', 'Newyork NY','Indiana IN','Florida FL'), Score=c(62.345,47.734,55.867,74.256,31.901)) df1
Generate Row number to the dataframe:
Row number is generated and stored in a column
df1$row_num <- seq.int(nrow(df1)) df1
so the resultant dataframe will be
