r-car

I am am trying to load a simple dataset using: library(car) but I get the following error: Error in library("car") : there is no package called 'car' Does anyone have an idea why this happens and how to solve it? If you don't currently use an IDE (or even if you do), the following will install the package: install.packages("car") Before then running library("car") You should heed @Iris's advice and use a RStudio if you don't already to manage just this sort of task. You forgot to install the package before you tried to load it. Do you use a IDE (integrated development environment)? I can
