R Split Dataframe By Row Number, In Example 1, I’ll explain how to divide a data table into two different parts by the positions of the data rows. I set nrow(d1) = 3, that I need to split into multiple dataframes that will contain every 10 rows of df , and every small dataframe I will write to separate file. The split function allows dividing data in groups based on factor levels. 1000 rows, and I want to split it randomly into 8 smaller dataframes each containing 100 element. For example, a|b b|c to become a b b c within a data frame.
