There is a very simple way to select a number of rows using the R index for rows and columns. This lets you CLEANLY split the data set given a number of rows - say the 1st 80% of your data. In R all rows and columns are indexed so DataSetName[1,1] is the value assigned to the first column and first row of "DataSetName".Coding is the process of creating instructions that computers then interpret and follow. Coding is also known as programming – even though a lot of people would argue there is a slight difference between the two, coding and programming still reference the same general process in the long run.
