Error: unexpected '$' in "$". I keep getting this error every time i try to name my list

[Similejesu]

I am new to R. I just started 2 days ago, I was following along with my instructor on the topic of naming vectors. I had seen an example done, and decided to do on my own.

list('Chicago' = 1, 'New York' = 2, 'Los Angeles' = 3)

$Chicago

Ever y time I run this code I keep getting the error message Error: unexpected '' in ""

You have to store the value of the list() function in a variable. Compare these two versions of the code.

#first version
list('Chicago' = 1, 'New York' = 2, 'Los Angeles' = 3)
$Chicago
[1] 1

$`New York`
[1] 2

$`Los Angeles`
[1] 3

$Chicago
Error: unexpected '$' in "$"

#second version
MyList <- list('Chicago' = 1, 'New York' = 2, 'Los Angeles' = 3)
MyList$Chicago
[1] 1
