How to Make a Histogram with ggplot2 Now we can create the histogram. Regardless of the type of graph we are creating in ggplot2, we always start with the ggplot() function, which creates a canvas to add plot elements to. It takes two parameters. The first argument is a data frame....
Combine the plots over multiple pages If you have a long list of ggplots, say n = 20 plots, you may want to arrange the plots and to place them on multiple pages. With 4 plots per page, you need 5 pages to hold the 20 plots. The functionggarrange()[ggpubr] provides a convenient...
R and Excel go together like macaroni and cheese. There’s no need to choose one over the other, as there are numerous packages and extensions that allow them to work together. Just because you have an xlsx file doesn’t mean you can’t analyze it with R
In the below code, We will build three different histograms using the R’s in-built dataset iris and then assign one by one to an R object. Finally, we will use cowplot functionplot_grid()to combine the two plots of our interest. #building the first plot plot_histogram_SL <- ggplot(...

Another common mistake is to misspell a function, a variable, a dataset, an object or a package’s name, for example: ## typo in function name: maen(c(1, 7, 13)) ## Error in maen(c(1, 7, 13)) : could not find function "maen" ## typo in variable name: summary(ggplot2::...
In this example, both point size and color are mapped to different variables. Output: Change Point Size in Graphs Usingggplot()in R We can useggplot()to customize and change point size in graphs in R. To get started, let’s create a basic scatter plot usingggplot()with the default poin...
The function ‘cor’ can calculate the correlation on the scale of 0 to 1, in a pairwise fashion between all samples, then visualise on a heatmap. There are many ways to create heatmaps in R, here I use ‘pheatmap’, the only argument it requires is a matrix of numeric values. We...
