Using the plotrix package to make a twoord plot. My attempts look like this
The problem I have is that it automatically does not plot the full left
As you didn't provide your data or your code, I offer this as an example:
library(plotrix) twoord.plot(2:10, seq(3, 7, by=0.5) + rnorm(9), 1:15, rev(60:74) + rnorm(15), type= c("l", "l"), xaxt = 'n', yaxt = 'n')
