The root cause is that column 1 is a factor. So what you get is really a set of parallel boxplots each based on one observation.
plot.default() is one way out, but you may need to generate the x-axis labels yourself. I.e., x <- factor(LETTERS[1:10]) y <- rnorm(10) plot(x,y) plot.default(x,y) For full control, recode the factor to a numeric variable.
