Is it valid to assign a slice of an array or vector to an overlapping slice of the same object? R seems to do the right thing but I can't find anything where it promises to. > a <- 1:12 > a[4:12] <- a[1:9] > a [1] 1 2 3 1 2 3 4 5 6 7 8 9 > b <- 1:12 > b[1:9] <- b[4:12] > b [1] 4 5 6 7 8 9 10 11 12 10 11 12

Legend titles work in linear plots: curve(1/x, xlim = c(0, 1)) legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1, title = 'Legend Title') But when you change to a log plot on either dimension things get screwy: curve(1/x, xlim = c(0, 1), log = 'y') legend(x = 'topright', inset = 0.04, legend = '1/x', lty = 1,
