What font size is an inch tall?ġ inch is roughly equal to 72 points FONT HAVE 3 ELEMENTS: X-HEIGHT – height of the lowercase “x” character. To change the axis scales on a plot in base R, we can use the xlim() and ylim() functions.
How do I change the scale of a plot in R?
(Re)start R so that it reads in the new settings.Count the number of uncommented non-blank lines in the file and note the number of your newly added line.Modify the user or system-wide Rdevga to add your desired font.sub: sub-title It’s placed at the bottom of x-axis. Change the order of the item in the legend. Change legend theme: background color, legend box border, font size and color.
In order to avoid repeating code we will use the following function to plot two Bessel functions in R ( J_0(x) and J_2(x)): plotl <- function(. In the following sections we will explain how to customize the most common arguments of the function. Recall that there are even more arguments you can use, but we listed the most common, so type args(legend), ?legend or help(legend) for additional information. Horiz = FALSE # Horizontal (TRUE) or vertical (FALSE) legend Pch, # Add pch symbols to legend lines or boxesīty = "o", # Box type (bty = "n" removes the box)īg = par("bg") # Background color of the legendīox.lwd = par("lwd"), # Legend box line widthīox.lty = par("lty"), # Legend box line typeīox.col = par("fg"), # Legend box line color Legend, # Vector with the name of each groupįill, # Creates boxes in the legend with the specified colorsĬol = par("col"), # Color of lines or symbolsīorder = "black", # Fill box border color The summarized syntax of the function with the most common arguments is described in the following block: legend(x, y, # Coordinates (x also accepts keywords) The legend function allows you to add a legend to a plot in base R.
