Creating named objects

• You can assign (memorize) an object with <-

• Names are case-sensitive: bob != Bob

• . is legal but not if followed by number and starting with it

• 'if, for, function, next TRUE are reserved

You should follow a naming conventions (usually follow project guidelines).

For naming temporary object:

• vectors: x, y z

• matrices: A, B, … , X, Y, Z

• integer indexes: i, j, k

• object size: n, m, p or nx, ny, etc

Tip:

(x <- 1:3) # allows you to print the object
