24 maj 2024 · cex stands for "character expansion." It is used to control the size of text, points, and other plot elements in R. How do you change the size of the main title in a plot? Use the cex.main parameter within the plot () function. For example, plot (x, y, main = "Title", cex.main = 2) increases the main title size.
cex decides the size of plotting characters (pch); cex.lab decides the size of the text labels on the axes; cex.axis decides the size of the numbers on the tick marks.
12 paź 2023 · cex stands for “character expansion.” It’s a parameter in R that allows you to adjust the size of text, symbols, and other graphical elements within your plots. You can think of it as a scaling factor that determines the size of these elements relative to the default size. Let’s start with the basics.
The graphical parameter cex determines the size of various things in base R plots, from labels to point sizes. cex = 1 is the default size, cex = .5 is 50% smaller, cex = 1.5 is 50% larger. My question is what exactly cex uses to scale circular point sizes.
The cex = argument allow you to change the size of the plotting symbol. This argument works in the same way as the other cex arguments we’ ve already seen (i.e. cex.axis) and requires a numeric value to indicate the proportional increase or decrease in size relative to the default value of 1.
In R, 'cex' is a graphical parameter that controls the size of text and symbols in plots. It stands for 'character expansion' and is used to modify the default size of points, axis labels, and other text elements to improve the clarity and visual appeal of data visualizations.
