[DOCX File]Lab 2: Manipulating Dataframes
https://info.5y1.org/r-built-in-dataset_1_cdb874.html
R offers several built-in dataframes. For this activity we will use the “mtcars” dataset that contains 11 variables and 32 cases representing different models of cars. The goal is to create a new variable for this dataframe that represents the engine displacement per cylinder in cubic inches for each vehicle.

Make sure the built-in “airquality” dataset is available for use in subsequent commands. It would be wise to reveal the first few records of air quality with head() to make sure that . air quality is available. This will also show you the names of the columns of the air quality dataframe which you will need to …

R makes use of “NA” to indicate a blank or missing value, so before reading in a data set with blanks or missing values, replace each blank or missing value with “NA” (not including the quotes). Note that for many R functions to work properly with a data set with missing values, the argument na.rm=T must be included, e.g.: > mean(x, na ...

The sample data is a built-in dataset about cars from the 1970's in tabular form, used here as a quick example. We can recognise immediately the code that will be executed by R as marked by {r} and usually referred to as code chuncks. The first chunck is a set-up parameter:
