Hello, R experts I am a new user of rgl package. I want axis label to be parallel to the axis. However, I cannot find any options in package manual. Could you show me how to how to make label be parallel to crresponding axis. Especially, Z axis label, in case that it is long, protrudes out of the plot and invades the plot. Please, let me know. I spent every night and day of even a month. TK Kim [[alternative HTML version deleted]]
