Remove all box around a plot except bottom line (base graphics)
That's pretty similar to call axis function, i.e.
?plot(rnorm(100), yaxt="n", bty="n")
?usr <- par("usr")
?## lines(usr[c(1,2)], usr[c(3,3)], xpd = TRUE)
?axis(1, ...) # where 1 is bottom, 2 left, 3 top, and 4 right sides of
the plot box)
Best

To make the plot clearer I have removed the axes but I wish to remove all the boz except the bottom horizontal line. Using the bty parameter does not seem to enable me to just leave the horizontal line at the foot. I can get the "l" version to remove everything except the left hand side and the base. I could also remove the entire box but that looks odd. Am I reading the documentation incorrectly or is it really impossible?
It's not something that `bty` can specify or `box()` can do, but you
can draw a line using lines() or segments().? For example:
?plot(rnorm(100), yaxt="n", bty="n")
?usr <- par("usr")
?lines(usr[c(1,2)], usr[c(3,3)], xpd = TRUE)
You might not even need the lines() call if you don't care how far the
axis extends.
