I am trying to figure how to use different coordinate systems for x and y coordinates in the
grid.text() functions (or any other similar functions in R).
In the example below I'd like to set the Y coordinates of the
text() function at 10% from the bottom of the screen instead of using the scale of the Y scale. I can do it with
grid.text() with y = 0.1 but I do not know how to set X positions of
grid.text() to the X scale of the plot. Basically, I'd like to mix the capabilities of
I know that
grid.text has an option of passing units but I can't figure out how to use the units from the plot.
library(grid) test= data.frame( x = c(1,2,3), y = c(12,10,3), n = c(75,76,73) ) par(mar = c(13,5,2,3)) plot(test$y ~ test$x,type="b") text(x=test$x, y=-2, label=test$n, xpd=T)
