Hi helpers.  

I have the following problem and I need some help When using grid.edit inside a pdf device it applies the changes on a second plot, not erasing the first one.
Here it is an example.  


produces a two pages pdf document, one with and one without the changes inttroduced by grid.edit  

If I use  


it produces the error:  

Error en editDLfromGPath(gPath, specs, strict, grep, global, redraw) :   'gPath' (legend) not found  

May anybody tell me how to save just the edited plot on the pdf file?  

Thanks in advance
