I have to write a document and the instructions are really stricts. The text size has to be 7pt inside all figures (axis labels, ticks labels, legends). For some reasons I use the base graphics package and cannot use extra packages like ggplot2. In the options of "graphics" ( ?par
), I only see this cex
parameter and derivatives that permit to fix the text size relative to a default size.
What is the default font size of R graphics ?
For all of R's graphical devices, the default text size is 12 points but it can be reset by including a pointsize
argument to the function that opens the graphical device. From ?pdf
:
pointsize: the default point size to be used. Strictly speaking, in bp, that is 1/72 of an inch, but approximately in points. Defaults to '12'.
For example, open a device like this:
## pdf
pdf("plot.pdf", pointsize=7)
## bitmap
bmp("plot.bmp", pointsize=7)
## graphics window on screen
x11(pointsize=7)
## etc., etc. (See ?Devices for a list of available graphics devices.)
and then, after plotting to it, close it with dev.off()
.
