Hi, All,

I am trying to use R to make the following type of boxplot while I couldn't
find a way to do it.

My dataset looks like X1 Y1 X2 Y2.... SPLIT. The split highlights my
experiment details and both x and y are continuous numerical values.  I
need to plot y vs. x with split as legend and boxplot has to be used for
all splits. May I ask how to get it? Currently available boxplot only
applies on the case that X axis is character.

Thanks

Qintao
