The dplyr package for R is described as a package providing a grammar for data manipulation. It has the entry points you would expect for wrangling your data frame in one package. We will use the dplyr package against the baseball player statistics we used earlier in this chapter.

We read in the player data and show the first few rows:

players <- read.csv(file="Documents/baseball.csv", header=TRUE, sep=",")
head(players)

We will be using the dplyr package, so we need to pull the package into our notebook:

library(dplyr)
