[R] barplot_add=TRUE

[Sibylle Stöckli]

Dear Gerrit

Thanks a lot. "rbind" seems to be the right function. Unfortunately there is a shift in the x-axis (see pdf). There are 52 trapcatch values each, m and w, but m$trapcatch and w$trapcatch are shifted up to x-value 60. 
The follow-up lines for temp and humidity are fine. 

Thanks
Sibylle
