Line Graph is plotted using plot function in the R language. It is a generic function, meaning, it has many methods which are called according to the type of object passed to plot().. Consider the following sample data: 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. Line charts are often displayed together with confidence intervals. More than one line can be drawn on the same chart by using the lines() function. The most used plotting function in R programming is the plot() function. For example, to create a plot with lines between data points, use type=”l”; to plot only the points, use type=”p”; and to draw both lines and points, use type=”b”: If we want to draw a basic line plot in R, we can use the plot function with the specification type = “l”. r documentation: Add horizontal and vertical lines to plot. If you continue to use this site we will assume that you are happy with it. For that purpose you can use the curve function, specifying the function and the X-axis range with the arguments from and to. change the size of points and outlines. Similarly, xlab and ylabcan be used to label the x-axis and y-axis respectively. Feel free to suggest a … The line graphs can be colored using the color parameter to signify the multi-line graphs for better graph representation. Ideally, it would be possible to add a name to each number (e.g. For example, to create a plot with lines between data points, use type=”l”; to plot only the points, use type=”p”; and to draw both lines and points, use type=”b”: It gets the slope and the intercept to use from the lsfit() , respectively line() . Creating R ggplot2 Line plot. type – type could be any of the below values ‘p’ – points Finally, it is important to note that you can add a second axis with the axis function as follows: We offer a wide variety of tutorials of R programming.
