R is Not So Hard, Part 12: Creating Histograms & Setting Bin Widths

by guest

by David Lillis, Ph.D.

This is Part 12 in my R Tutorial Series: R is Not so Hard.  Go back to Part 11 or start with Part 1.

I’m sure you’ve heard that R creates beautiful graphics.

It’s true, and it doesn’t have to be hard to do so.  Let’s start with a simple histogram using the hist() command, which is easy to use, but actually quite sophisticated.

First, we set up a vector of numbers and then we create a histogram.

B <- c(2, 4, 5, 7, 12, 14, 16)
hist(B)

When Listwise Deletion works for Missing Data

You may have never heard of listwise deletion for missing data, but you’ve probably used it.

Listwise deletion means that any individual in a data set is deleted from an analysis if they’re missing data on any variable in the analysis.

Although the simplicity of it is a major advantage, it causes big problems in many missing data situations.

Five Common Relationships Among Three Variables in a Statistical Model

Including Z in the model often leads to the relationship between X and Y becoming more significant because Z has explained some of the otherwise unexplained variance in Y.

An example of this kind of covariate is when an experimental manipulation (X) on response time (Y) only becomes significant when we control for finger dexterity levels (Z).

Ten Ways Learning a Statistical Software Package is Like Learning a New Language

Someone recently asked me if they need to learn R. In responding, it struck me that this is another way that learning a stat package is like learning a new language.

The metaphor is extremely helpful for deciding when and how to learn a new stat package, and to keep you going when the going gets rough.

R Is Not So Hard! A Tutorial, Part 11: Creating Bar Charts

In Part 11, let’s see how to create bar charts in R. Let’s create a simple bar chart using the barplot() command, which is easy to use. First, we set up a vector of numbers. Then we count them using the table() command, and then we plot them. The table() command creates a simple table of counts of the elements in a data set.

R Is Not So Hard! A Tutorial, Part 10: Creating Summary tables with aggregate()

In Part 10, let’s look at the aggregate command for creating summary tables using R.

You may have a complex data set that includes categorical variables of several levels, and you may wish to create summary tables for each level of the categorical variable. For example, your data set may include the variable Gender, a two-level categorical variable with levels Male and Female. Your data set may include other categorical variables such as Ethnicity, Hair Colour, the Treatments received by patients in a medical study, or the number of cylinders in motor vehicles.
