WebJul 23, 2024 · Splitting a data set into smaller data sets randomly For randomly splitting a data set into many smaller data sets we can use the same approach as above with a slight modification. In essence, we are going to randomly shuffle observations of our source data set first, and then apply the sequential splitting. The following code shows how to use the subset()function to select rows and columns that meet certain conditions: We can also use the (“or”) operator to select rows that meet one of several conditions: We can also use the &(“and”) operator to select rows that meet multiple conditions: We can also use the … See more The following code shows how to subset a data frame by column names: We can also subset a data frame by column index values: See more The following code shows how to subset a data frame by excluding specific column names: We can also exclude columns using index values See more The following code shows how to subset a data frame by specific rows: We can also subset a data frame by selecting a range of rows: See more
