The function you use depends on your file type. Like a list, but must be all of the same classīeyond the scope of this level - computational efficiency Reading and saving data Reading data in. Can not use $ for referencing columns ( used). Entire structure is one class (all numeric or character etc). A grid like structure (similar to ames). Any data point that has something other than numbers in it will (typically) default to being of class character. Free text fields will be of class character. character is the highest-level 'catch-all' class. Functions will respond differently based on the class of data you feed them. Classes are closely related to Structures (the next topic). There are many classes, most (and the common ones) are nice and clear. Each data point (value within a cell) will have a class. Best practise is using relative directory paths!. The letters T and F are abbreviations for TRUE and FALSE. Double question mark to search for commands. #Mac terminal commands books +github code#
