在R中绘制+更改字体大小

Question

I want to reduce the label expression "hola" in this instruction:

axis(1, at = c(32.65), labels = expression("hola")) 

How can I do this?

Answer 1

Use the argument cex.axis . This is a scaling value relative to 1, thus values <1 reduce the font size, and values >1 increase the font size:

plot(1:50)
axis(1, at = c(32.65), labels = expression("hola"), cex.axis=2)
axis(1, at = c(45), labels = expression("hola"), cex.axis=0.5)

Answer 2

Use cex.axis to change the label size.

For instance:

axis(1, at = c(32.65), labels = expression("hola"), cex.axis=0.8)
