GGPlot2 Essentials for Great Data Visualization in R Key R functions Key function:geom_density()(for density plots). Key arguments to customize the plots: color, size, linetype: change the line color, size and type, respectively fill: change the areas fill color (for bar plots, histograms ...
library(plotly)p<-ggplot(diamonds,aes(x=price))+geom_density(aes(fill=color),alpha=0.5)+ggtitle("Kernel Density estimates by group")fig<-ggplotly(p)fig These plots were inspired byggplot2 documentation. What About Dash? Dash for Ris an open-source framework for building analytical applications...
To avoid overlapping (as in the scatterplot beside), it divides the plot area in a multitude of small fragment and represents the number of points in this fragment. There are several types of 2d density plots. Each has its proper ggplot2 function. This post describes all of them. # ...
Basic density plots library(ggplot2) # Basic density p <- ggplot(df, aes(x=weight)) + geom_density() p # Add mean line p+ geom_vline(aes(xintercept=mean(weight)), color="blue", linetype="dashed", size=1) Change density plot line types and colors ...
ggplot(dfs, aes(x=values)) + geom_density(aes(group=ind)) This is getting closer, but it’s not easy to tell each one apart. Let’s try colour the different methods, based on theindcolumn in our data frame. ggplot(dfs, aes(x=values)) + geom_density(aes(group=ind, colour=ind)...
A density plot is a representation of the distribution of a numeric variable. It is a smoothed version of the histogram and is used in the same kind of situation. Here is a basic example built with the ggplot2 library. Density Section Density theory Density plots are built in ggplot2 ...
ggplot2.density function is from easyGgplot2 R package. An R script is available in the next section to install the package. At the end of this tutorial you will be able to draw, with few R code, the following plots: ggplot2.density function is described in detail at the end of...
An advantage Density Plots have over Histograms is that they're better at determining thedistribution shapebecause they're not affected by the number of bins used (each bar used in a typical histogram). A Histogram comprising of only 4 bins wouldn't produce a distinguishable enough shape of di...
Finally, the default versions ofggplotplots look more "polished."ggplot2charts just look better than the base R counterparts. Having said that, let's take a look. Let's take a look at how to create a density plot in R usingggplot2: ...
