Equality

The most basic form of comparison is equality. Let's briefly recap its syntax. The following statements all evaluate to TRUE $($feel free to try them out in the console$).$

$3==(2+1)$

"intermediate" $!="$r$"$

TRUE $!=$ FALSE

"Rchitect" $!=$ "rchitect"

Notice from the last expression that R is case sensitive: $"$R$"$ is not equal to $"$r$".$ Keep this in mind when solving the exercises in this chapter!

In the editor on the right, write R code to see if TRUE equals FALSE.

Likewise, check if $-6*14$ is not equal to $17-101.$

Next up: comparison of character strings. Ask R whether the strings "useR" and "user" are equal.

Finally, find out what happens if you compare logicals to numerics: are TRUE and $1$ equal?
