What is the difference between <-, = and ==?
This <- is used for assignment; to assign a value to a variable (e.g. x <-3). While <- is more frequently used, the equal to sign (=) is also used for assignment in specific situations (such as function arguments). But we recommend you use <- in R programming to avoid future conflicts.
The double equal to (==) sign verifies whether two values are equal (e.g. x==5 returns TRUE or FALSE)

To make matters more confusing, there is also -> assignment
3 -> x which assigns 3 to x. R for fun, I guess

You are right. To avoid all these confusions and conflicts, it is recommended that programmers use <- for assignments. JUST TO BE ON THE SAFER SIDE.
