Be sure to use dplyr::filter and not stats::filter

To this end ensure that the library dplyr is loaded.

e.g.

library(dplyr)

filter(mpg, year == 2002)

Export using write.csv
First set your file directory, or else it will default to Documents.
You can set it via Session > Set Working Directory > To Source File Location (i.e. where your R script is stored). Or specify it using setwd

setwd("C:/Users/me/Desktop/MyFile")
write.csv(mpg, file = "mpgdataset.csv")

Hey! There is a function called data() if you run that it will show you all preinstalled data sets. : )
