Reset par(xaxp) in plot

R-Helpers; This seems simple to set graphic parameter, but I tried plot a graph with 10 intervals in x axis with par(xaxp = c(0, 150, 10) but to no avail: par(xaxp =c (0, 150, 10)) plot(age, y18, type="n", ylab="Height (m)", xlab=" age (Yrs)", font = 2) lines(age, y6, lty = 4, lwd = 2) lnes(age, y10, lty = 1, lwd =2) lines(age, y14, lty = 2, lwd =2) lines(age, y18, lty = 3, lwd = 2) abline(v=50) The plot shown only 3 intervals with tick at 0, 50, 100, and 150. and
par()$xaxp
[1] 0 150 3
...
What did I miss?
xaxp is a bit tricky since it gets calculated and *set* by routines like plot. You can, however, plot without axes, set xaxp, and then use axis(): plot(1:10,axes=F) par(xaxp=c(1,10,99)) axis(1) axis(2) box() (Arguably, plot(1:10,xaxp=c(1,10,99)) could be coerced to work, but it currently does not.)
