Download the data set
Before we get rolling with the EDA, we want to download our data set. For this example, we are going to use the dataset produced by my recent science, technology, art and math (STEAM) project.
Head
To begin, we are going to run the head function, which allows us to see the first 6 rows by default. We are going to override the default and ask to preview the first 10 rows.
dim and Glimpse
Next, we will run the dim function which displays the dimensions of the table. The output takes the form of row, column.
Summary
We then run the summary function to show each column, it’s data type and a few other attributes which are especially useful for numeric attributes. We can see that for all the numeric attributes, it also displays min, 1st quartile, median, mean, 3rd quartile and max values.
Skim
Next we run the skim function from the skimr package. The skim function is a good addition to the summary function. It displays most of the numerical attributes from summary, but it also displays missing values, more quantile information and an inline histogram for each variable!

Introduction
Importing data into R is a necessary step that, at times, can become time intensive. To ease this task, the RStudio IDE includes new features to import data from: csv, xls, xlsx, sav, dta, por, sas and stata files.
Importing data
The data import features can be accessed from the environment pane or from the tools menu. The importers are grouped into 3 categories: Text data, Excel data and statistical data. To access this feature, use the "Import Dataset" dropdown from the "Environment" pane:
Importing data from Text and CSV files
