FILTER command problem

filter(dina,"hotel"=='City Hotel")
+
Hello,
I entered the above (which is wrong) but when I'm trying to run it,it doesn' recognize it as wrong .Instead it 's going to next row with the add (+) symbol. So I can't go on with another command to run it properly.
I'd appreciated it if s/b could help me.
Thank you in advance.

you have 3 uses of the double quote symbol and 1 use of a single quote.
This is unbalanced and will cause chaos in the R Session, quotes should be balanced.

Thank you! Have a nice day.
