Use a single color # box plot ggplot(ToothGrowth, aes(x=dose, y=len)) + geom_boxplot(fill='#A4A4A4', color="darkred") # scatter plot ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point(color='darkblue') Change colors by groups Default colors The following R code changes the color...
In order to use the functions of the ggplot2 and ggvenn add-on packages, we need to install and load the two packages in R: install.packages("ggplot2")# Install & load ggplot2 packagelibrary("ggplot2")install.packages("ggvenn")# Install & load ggvennlibrary("ggvenn") ...
Use shared legend for combined ggplots To place a common unique legend in the margin of the arranged plots, the functionggarrange()[in ggpubr] can be used with the following arguments: common.legend = TRUE: place a common legend in a margin ...
# Create a ggplot with white background p + theme( plot.background = element_rect(fill = "white"), panel.background = element_rect(fill = "white"), axis.line.x = element_line(color = "grey") ) Create a ggplot with transparent background. The easiest solution is to use the theme...
Then, we might try to use the lines function as shown below:lines(1:10) # Try to add lines to non-existent plot # Error in plot.xy(xy.coords(x, y), type = type, ...) : # plot.new has not been called yetUnfortunately, the RStudio console returns the error message “plot.new...
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. Here we want to use home_data. The second argument is a mapping from ...
