To do this, were going to use the subset command. We will be using mtcars data to depict the example of filtering or subsetting. Note: The & symbol represents AND in R. In this example, we only included one AND symbol in the subset() function but we could include as many as we like to subset based on even more conditions. The idea behind filtering is that it checks each entry against a condition and returns only the entries satisfying said condition. In addition, if your vector is named, you can use the previous and the following ways to subset the data, specifying the elements name as character.

Existence of rational points on generalized Fermat quintics, Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. As an example, you may want to make a subset with all values of the data frame where the corresponding value of the column z is greater than 5, or where the group of the w column is Group 1. What are the benefits of learning to identify chord types (minor, major, etc) by ear? The point is that you need a series of single comparisons, not a comparison of a series of options. The subset() method in base R is used to return subsets of vectors, matrices, or data frames which satisfy the applied conditions.
