Direct variable output¶
A variable or a constant can be displayed directly in both workspace and scripts.
x <- 1 2 3 x 1 2 3 'abc' abc
 and [) functions¶
-  is used to display the content of a value and print a return at the end.
- [) is the same as the function  except that there is no a new line at the end.
<-x 1 2 3
The direct variable output can’t display all values if screen limititation is reached. Therefore, the function  allows display all rows and columns, especially when you have a large table.
