Aug 04, 2014 · Plot.ly is a great tool for easily creating online, interactive graphics directly from your ggplot2 plots. The process is surprisingly easy, and can be done from within R, but there are enough steps that I describe how to create graphics like the one below in a separate post.
The data set must be a data.frame object. Example syntax for ggplot() specification (italicized words are to be filled in by you): ggplot(data, aes(x=xvar, y=yvar)) If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping. data: The data to be displayed in this layer. There are three options: If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot… ggplot2 tries to use the fewest number of legends to accurately convey the aesthetics used in the plot. It does this by combining legends where the same variable is mapped to different aesthetics. The figure below shows how this works for points: if both colour and shape are mapped to the same variable, then only a single legend is necessary.

Very nice answer. I do something very similar with quartz(height=11, width=8.5) to get a new plot window, followed by the ggplot() stuff, followed by quartz.save('fname.pdf'). The end result is the same and I never have to remember those pesky dev.off() commands. – Curt F. Apr 13 '15 at 2:18 Create a plot object using the function ggplot().
Top 50 ggplot2 Visualizations - The Master List (With Full R Code) What type of visualization to use for what sort of problem? This tutorial helps you choose the right type of chart for your specific objectives and how to implement it in R using ggplot2.

The first argument specifies the result of the Predict function. The predictor is always plotted in its original coding. If rdata is given, a spike histogram is drawn showing the location/density of data values for the \(x\)-axis variable. 12/10/2020 In the ggplot() function we specify the data set that holds the variables we will be mapping to aesthetics, the visual properties of the graph. The data set must be a data.frame object.
To be more specific, I have the following 2 visuals: Density ridgeline plots. The density ridgeline plot is an alternative to the standard geom_density() function that can be useful for visualizing changes in distributions, of a continuous variable, over time or space.

ggplot (data = iris, aes (x = Sepal.Length, y = Sepal.Width,shape = Species, color = Species)) + geom_point () We plot the points using geom_point (). The function qplot() [in ggplot2] is very similar to the basic plot() function from the R base package. It can be used to create and combine easily different types of plots. However, it remains less flexible than the function ggplot(). This chapter provides a brief introduction to qplot(), which stands for quick plot.
It provides a more programmatic interface for specifying what variables to plot, how they are displayed, and general visual properties. Plotting with ggplot2. There are two main systems for making plots in R: “base graphics” (which are the traditional plotting functions distributed with R) and ggplot2, written by Hadley Wickham following Leland Wilkinson’s book Grammar of Graphics. We’re going to show you how to use ggplot2.
By default, the labels are displayed on the top and right of the plot. If "x", the top labels will be displayed to the bottom. If "y", the right-hand side labels will be displayed to the left. Can also be set to "both" showStrips: boolean to determine if each plot's strips should be displayed.

It’s the default specification of the ggplot2 package to show legends on the right side outside the plot area. The following example explain how to move such a legend to different positions. Example 1: ggplot2 Legend at the Bottom of Graph. This Example explains how to show a legend at the bottom of a ggplot2 plot in R.
ggplot(diamonds, aes(x=carat, color=cut)) # Each category of the 'cut' variable will now have a distinct color, once a geom is added. Very nice answer. I do something very similar with quartz(height=11, width=8.5) to get a new plot window, followed by the ggplot() stuff, followed by quartz.save('fname.pdf').

This R tutorial describes how to create a box plot using R software and ggplot2 package.. The function geom_boxplot() is used. A simplified format is : geom_boxplot(outlier.colour="black", outlier.shape=16, outlier.size=2, notch=FALSE)
Note that the creation of density plots using ggplot uses many of the same embedded commands that were customized above.
There are three options: If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot… Example 3 explains how to add user-defined colors to our plot. For this task, we have to use the scale_fill_manual function as shown below: ggplot ( data, aes ( x = group , y = value , fill = group ) ) + # Manually specified filling color geom_boxplot ( ) + scale_fill_manual ( breaks = group , values = c ( "#1b98e0" , "#353436" , "yellow" , "red" , "green" ) ) Spaghetti plot using ggplot2 . It is possible to make a spaghetti plot using base R graphics using the function interaction.plot(). We however do not discuss this approach here, but go directly to the approach using ggplot2. We want to exactly reproduce figure 3 of the article that actually has four sub-figures.
