Read the data file to a data frame ss16wa, and only retain columns "PWGTP", "AGEP", "WAGP", "VALP", "WKHP", "CIT", "ACCESS". (2)

Murrr4er [49]

Answer:

Data Frame

A data frame is used for storing data tables. It is a list of vectors of equal length. For example, the following variable df is a data frame containing three vectors n, s, b.

> n = c(2, 3, 5)

> s = c("aa", "bb", "cc")

> b = c(TRUE, FALSE, TRUE)

> df = data.frame(n, s, b) # df is a data frame

Built-in Data Frame

We use built-in data frames in R for our tutorials. For example, here is a built-in data frame in R, called mtcars.

The top line of the table, called the header, contains the column names. Each horizontal line afterward denotes a data row, which begins with the name of the row, and then followed by the actual data. Each data member of a row is called a cell.

To retrieve data in a cell, we would enter its row and column coordinates in the single square bracket "[]" operator. The two coordinates are separated by a comma. In other words, the coordinates begins with row position, then followed by a comma, and ends with the column position. The order is important.
