  1. There are many functions other than read.table() for importing data. For example, the functions read.csv and read.delim are specific for importing comma-separated and tab-separated text files. In practice, these functions do the same thing as read.table, but they don’t require you to specify a sep argument. Personally, I always use read.table() because it always works and I don’t like trying to remember unnecessary functions.
