You probably have discovered that R usually gives you different size of fonts in different figures. That is because a numerical value (cex in par function) giving the amount by which plotting text and symbols is magnified relative to a default value. This starts as ‘1’ when a device is opened, and is reset when the layout is changed, e.g. by setting ‘mfrow’.
But the final fonts size for the main title (or axis, lab, sub) is determined by the product of the three variables, ps, cex, and cex.main (or cex.axis, cex.lab, cex.sub), respectively.
So if you want 12 points fonts in the title, you may set the following options
par(ps = 12, cex = 1, cex.main = 1)
Update: it is also possible to have different fonts in axes and title, use cex.main, cex.lab, cex.sub to change the magnification, respectively.
Thanks! I was going crazy trying to fit my hclust text!
Hi Thank you for information
could with how to changing the axis text (8points) and axis labels (9 points) to different font size font size?
Try cex.main, cex.lab, and cex.sub.
Thank you so much!
Thanks for sharing
Excellent
Thank you!!!!!
Thanks a lot!
Thanks! Just what I needed.
