![]() Having plots side by side makes things easier for the viewer and is good for comparisons. Grid.arrange(norm_plot, exps_plot, ncol = 2) I put both the normal and exponential random variables plot into one with ncol = 2. Multiple Graphs In One With grid.arrange()įrom the gridExtra package in R, multiple plots can be put into one graph with the use of the grid.arrange() function. Labs(x = "\n Value Of Exponential Random Variable", y = "Count \n", title = "Simulated Exponential Random Variables \n") Geom_histogram(binwidth = 0.1, boundary = 2, col = "black", fill = "#b7b700") ![]() # Exponential Plot:Įxponentials <- rexp(n = 10000, rate = 3)Įxps_plot <- ggplot(data = NULL, aes(exponentials)) In the second plot, I simulate 10000 exponential random variables in R with the rexp() function with the rate of 3. Simulating Exponential Random Variables Plot Labs(x = "\n Number Of Standard Deviations (Z-Scores)", y = "Count \n", title = "Simulated Standard Normal Variates\n") Geom_histogram(binwidth = 0.1, boundary = 2, col = "black", fill = "#D5ADA4") cartesian, polar, 3-dimensional, maps etc) with attached traces of various compatible types (e.g. Chart Types versus Trace Types Plotly's figure data structure supports defining subplots of various types (e.g. Norm_plot <- ggplot(data = NULL, aes(normals)) How to design figures with multiple chart types in R. The results are plotted in ggplot2 in the form of a histogram. Values outside of 3 standard deviations are extreme cases or outliers. Most of the values will lie within 3 standard deviations from the mean of 0. library(ggplot2)įor the first plot, I simulate 10000 standard normal random variables (mean of 0 and variance of 1) in R. For installation of a R package use install.packages('pkg_name'). The original version of this post can be found on my website here.Ī good reference for ggplot2 in R is the R Graphics Cookbook by Winston Chang.īefore entering in the main code, make sure to load in the ggplot2 and gridExtra packages into R. The main R package that is used here is gridExtra. In this post, the focus is on having multiple plots in one graph in the programming language R. Lines(data$var2, as.numeric(data$group), col = 2)Īxis(2, labels = as.character(data$group), at = as.Hi there. Plot(data$var1, as.numeric(data$group), type = "l", Lines(as.numeric(data$group), data$var2, col = 2)Īxis(1, labels = as.character(data$group), at = as.numeric(data$group)) Plot(as.numeric(data$group), data$var1, type = "l", You can set the factor variable on the X-axis or on the Y-axis: par(mfrow = c(1, 2)) If you want to plot the data as a line graph in R you can transform the factor variable into numeric with the is.numeric function and create the plot. Consider the following sample data: # Dataĭata <- ame(group = as.factor(c("Group 1", "Group 2", "Group 3")), In addition to creating line charts with numerical data, it is also possible to create them with a categorical variable. Matplot(data, type = "l", main = "matplot function") You can plot all the columns at once with the function: # Plot all columns at once ![]() The matplot and matlines functionsĪ better approach when dealing with multiple variables inside a data frame or a matrix is the matplot function. Note that the lines function is not designed to create a plot by itself, but to add a new layer over a already created plot.
