Variable Name Challenge 1 Intro To R and R Studio #244
I would recommend including the reasoning for the answers that would not work as variables.
_age - We can only start variable names with letters or dots not followed by a number.
min-length - This contains a dash "-" character that can't be used when naming a variable. We can only use letters, numbers, dots, and underline "_" characters.
2widths - We can't start a variable name with a number.
I'd also recommend adding a question about a reserved word:
if - If is a special case called a reserved word. We use it for control structures that will be discussed at a later date.
