A lot of new R users fail to grasp what makes data frames more useful than matrices, or use data frames without even realizing they are not using matrices.
This is important because there are more tools for manipulating data frames than matrices. One tool is the split function... if you have a vector of values identifying how each row should be identified you can give that to the split function with your data frame and it will return a list of data frames (2 in this case). v <- rep( 0:6, length=1826 ) wkv <- ifelse( v < 5, "Weekday", "Weekend" ) ans <- split( DF, wkv ) ans$Weekday ans$Weekend Note that this is a fragile technique for generating wkv though... usually there will be a column of dates that can be used to generate wkv more consistently if your data changes.
