Where did you come across the expression? It’s very likely that this is just to get you thinking about evaluations and booleans in R. Essentially, work inside of the parentheses and work outward until there is nothing left to evaluate. Let’s work through it step by step:<\/p>\n

((111 >= 111) | !(TRUE)) & ((4 + 1) == 5)<\/code><\/p>\n

Step 1:<\/h3>\n

(111 >= 111)<\/code>. Well, this is TRUE<\/code> because 111 == 111. So now we have the following (TRUE | !(TRUE)) & ((4 + 1) == 5)<\/code>.<\/p>\n

Step 2:<\/h3>\n

!(TRUE)<\/code>. !<\/code> means “not” and simply reverses a boolean value. So, !TRUE<\/code> is the same as FALSE<\/code> and !FALSE<\/code> is the same as TRUE<\/code>. Therefore, we’re left with this: (TRUE | FALSE) & ((4 + 1) == 5)<\/code>.<\/p>\n

Step 3:<\/h3>\n

(TRUE | FALSE)<\/code>. |<\/code> means “OR” and checks to see if at least one<\/strong> of the conditions is TRUE<\/code>. Here we have two condtions, TRUE<\/code> and FALSE<\/code>. Since one of them is TRUE<\/code>, this whole expression evaluates to TRUE<\/code>. We therefore now have TRUE & ((4 + 1) == 5)<\/code>.<\/p>\n

Step 4:<\/h3>\n

((4 + 1) == 5)<\/code>. This is obviously TRUE<\/code> since 4 + 1 == 5<\/code>, so we now have TRUE & TRUE<\/code>.<\/p>\n

Step 5:<\/h3>\n

TRUE & TRUE<\/code>. &<\/code> means “and” and it checks to see that all<\/strong> of the conditions are TRUE<\/code>. Since our two conditions are TRUE<\/code> and TRUE<\/code>, it’s true that all conditions are TRUE<\/code> and therefore this evaluates to TRUE<\/code>. <\/p>\n

So, at the end of 5 steps of evaluation, we find that the entire expression evaluates to TRUE<\/code>. You’d benefit greatly from reading through the link @mtoto provided in the comments to help you understand this better.<\/p>\n

Hope that helps.<\/p>\n<\/p><\/div>\n
