Or, much simpler, use theselectargument of thesubsetfunction : you can then use the-operator directly on a vector of column names, and you can even omit the quotes around the names ! R> subset(df, select=-c(z,u)
In Example 1, I’ll illustrate how to drop certain columns of a data frame using the %in%-operator and the names function.The following R code checks whether the column names of our data frame (i.e. names(data)) are in a vector of variable names we want to remove (i.e. c(“x1...
