in R how to count the number of times a value appears and meet multiple criteria

example:

Colour   vehicle      city         type
red       car         London       Petrol
blue      truck       Paris        Diesel
red       car         NewYork      Electric
green     van         Barcelona    Petrol
black     motorbike   LosAngeles   Petrol

i.e. How to count number of times that "car" appears and it's "red" and "Petrol"

this is what I tried

sum(full_data$vehicle == "car"& full_data$Colour == "red"& 
  full_data$type == "Petrol")
