model.matrix error

Hello, could you help me how to solve this error?
I'm just trying to use 'model.matrix'. But it shows me 'Unexpected Symbol'.
I try all my way.. How can I do it? <- model.matrix(~0 + Fuel Type + Color,

why is there a zero 0 in there ?

I'm not good at Rstudio. I just learned it for a few days. so...I don't know why a zero in here... My professor just told me input that.

  1. if Fule Type is the name of the column, you should put it between ` chars because of the empty space. -> `Fule Type` instead of Fule Type

  2. something else: is the argument data = correct? because I do not see, where you load or generate before calling model.matrix()?
