Once you’ve added multiple layers and tweaks to a ggplot graph, how can you save that work so it’s easy to re-use? One way is to convert your code into a function. Another is to turn it into an RStudio code snippet. But the ggpackets package has a ggplot-friendlier way: Create...
Lines (ggplot2)) - Add lines to a graph. Facets (ggplot2)) - Slice up data and graph the subsets together in a grid. Multiple graphs on one page (ggplot2)) Colors (ggplot2)) 学了那么多语法,就在菜谱里面把握细节吧! 最后一个是https://stackoverflow.com/ ...
Plot one or several time series A time series is the visual representation of time-dependent data, this is, its a chart that represents the evolution of a variable through time. Generally, the pair of points are connected with lines and the decision of showing the points or not depends on...
To arrange multiple ggplot2 graphs on the same page, the standard R functions - par() and layout() - cannot be used. This R tutorial will show you, step by step, how to put several ggplots on a single page. The functions grid.arrange()[in the package gridExtra] and plot_grid()[...
GGPlot2 Essentials for Great Data Visualization in R geom_hline : Add horizontal lines A simplified format of the function geom_hline() is : geom_hline(yintercept, linetype, color, size) It draws a horizontal line on the current plot at the specified ‘y’ coordinates : libr...
