Today, I was wondering how to customize the appearance of the box-and-whisker plots. E.g., I wanted to remove the line around the box. However, the problem is, that the
border argument changes the color of all lines of the box-and-whisker plots simultaneously. So, if one has the create idea to set
border = "white" then the whiskers are also going to “disappear” and you have a white line representing your median.
As I could not find a solution on the internet dealing with exactly my problem, I fiddled around a little and figured some mighty settings which seem to be nearly undocumented as a whole. These settings allow you to customize the appearance of your box-and-whisker plots to a large extend. I know, some of the features have already been unveiled on stackoverflow (e.g. here). However, I could not find a complete documentation. Thus, this post.
