I reproduce some of the plots from Rstudio’s ggplot2 cheat sheet using Base R graphics. I didn’t try to pretty up these plots, but you should.
I use this dataset
The main functions that I generally use for plotting are
- Plotting Functions
plot: Makes scatterplots, line plots, among other plots.lines: Adds lines to an already-made plot.par: Change plotting options.hist: Makes a histogram.boxplot: Makes a boxplot.text: Adds text to an already-made plot.legend: Adds a legend to an already-made plot.mosaicplot: Makes a mosaic plot.barplot: Makes a bar plot.jitter: Adds a small value to data (so points don’t overlap on a plot).rug: Adds a rugplot to an already-made plot.polygon: Adds a shape to an already-made plot.points: Adds a scatterplot to an already-made plot.mtext: Adds text on the edges of an already-made plot.
- Sometimes needed to transform data (or make new data) to make appropriate plots:
table: Builds frequency and two-way tables.density: Calculates the density.loess: Calculates a smooth line.predict: Predicts new values based on a model.
All of the plotting functions have arguments that control the way the plot looks. You should read about these arguments. In particular, read carefully the help page ?plot.default. Useful ones are:
main: This controls the title.xlab,ylab: These control the x and y axis labels.col: This will control the color of the lines/points/areas.cex: This will control the size of points.pch: The type of point (circle, dot, triangle, etc…)lwd: Line width.lty: Line type (solid, dashed, dotted, etc…).
Discrete
Barplot
Different type of bar plot
Continuous X, Continuous Y
Scatterplot
Jitter points to account for overlaying points.
Add a rug plot
Add a Loess Smoother
Loess smoother with upper and lower 95% confidence bands
Loess smoother with upper and lower 95% confidence bands and that fancy shading from ggplot2.
Add text to a plot
Discrete X, Discrete Y
Mosaic Plot
Color code a scatterplot by a categorical variable and add a legend.
par sets the graphics options, where mfrow is the parameter controling the facets.
The first line sets the new options and saves the old options in the list old_options. The last line reinstates the old options.

HTML and CSS are two of the easier coding languages to learn and most people with an interest in becoming a web designer, or even people who have an interest in just being able to make simple changes to their own websites, should be able to master the basics fairly quickly. There are a plethora of online resources for leaning web design and also a number of free eBooks you can download to get you started.
Sometimes though, even the most seasoned of web designers will forget an HTML element, or how to format a CSS rule and will have to resort to online searches to make sure of the information. Having something to hand though is a better way of referencing things as you will not have to stop and perform a search query and dig through the results to find the information you need.
That is where the use of a “cheat sheet” will come in handy, these are sheets of information that are available on a wide variety of subjects that require you to memorize a lot of information, such as all the HTML and CSS tags and elements that you can use.
You can print out a cheat sheet and keep it handy on your desk so you can refer back to it if needed, you can also keep a folder on your computer if required with all your cheat sheets in one place.
There are a huge range of these available online, so we have put together a list of over 30 different options for you to download and start using to aid you in your coding of these two languages. A lot of these will cover the same information so it’s a case of taking a look through them all and saving the ones which are formatted how you like.
