I am using the package 'hydrogeo' https://cran.r-project.org/web/packages/hydrogeo/hydrogeo.pdf to create piper plot diagrams.
How can I increase font size of axes
rm(list=ls())
library(hydrogeo)
l <- list( Ca = c(43,10,73,26,32),
Mg = c(30,50,3,14,12),
Cl = c(24,10,12,30,43),
SO4 = c(24,10,12,30,43))
lp <- piper(l)
[email protected] = c(15,17,18,15,17)
[email protected] = c(4,1,3,5,2)
plot( lp, main="Piper-Hill Diagram of Water Quality", cex=1.2)
I try with a theme and cex.axis
