Loading and Handling Data
- A function is a way to tell the computer what to do. The c() function is short for “combine” so you essentially tell the computer (in the R language) to combine the values.You have to load and be able to handle data before you can chart it. No data means no chart. Enter the vector. It’s a structure in R that you use to store data, and you use it often. Use the c() function to create one, …
Basic Plotting
- It’s not that smart though. But at least it won’t crash on you.R has a plot() function that is kind of smart in that it adapts to the data that you pass it. For example, plot fakedata. It’s only a one-dimensional vector, so by default, R uses a dot plot with the values of the vector on the vertical axis and indices on the horizontal. However, try to plot the education data frame, as shown belo…
Using Arguments
- When you pass different valus to functions, you actually set the value of arguments. Change the values, and you get different output and charts. For example, the plot() function has a typeargument, which use to specify the type of chart you want. If you don’t specify, R will guess and use dots by default. Set type to “l” and you get a line chart. Y...
Additional Charts
- Although plot() can handle a good bit, there will be times when you want to use other chart types that the function doesn’t offer. For example, the function doesn’t provide a basic bar chart. Instead, use barplot(). And you get a basic bar plot. Like the plot()function, there are arguments to fiddle with to get what you want. Similarly, you can use boxplot()to see distributions. Just as eas…
Wrapping Up
- Most basic charts only require a couple of lines of code in R, and you can make customizations by changing argument values. Use function documentation, which usually includes code snippets at the end, to learn how to use a new function. Want more? The examples in this tutorial are just tip of the iceberg.
