How to Extract Two Columns of Data in R

Question

I have to extract two columns from this data set (Cars93 on MASS) and create a separate folder consisting only of the two columns MPG.highway and EngineSize. How do I go about doing this?

You can look at Cars93 on Mass and just get the first ten rows to see it.

Just use column names or index to extract the columns from the data.frame — akrun, Sep 18 '18 at 17:42

You can create a subset using the names directly using the subset function or alternately,

new_df <- Cars93[,c("MPG.highway","EngineSize")]
#or
new_df <- subset(Cars93, keep = c("MPG.highway","EngineSize"))
