[R-sig-Geo] problem with sp.layout in latest version of sp

[Tim Appelhans]

Dear list,
a while ago I implemented a function (rgb2spLayout) to convert an RGB 
RasterBrick/*Stack to a list which can then be used with spplot via the 
sp.layout argument in order to e.g. plot points on a Bing/Google Earth 
image. The code for the function is based on this blogpost:

https://procomun.wordpress.com/2013/04/24/stamen-maps-with-spplot/

and the function is part of a package called "Rsenal" and can be found here:

https://github.com/environmentalinformatics-marburg/Rsenal/blob/master/R/rgb2spLayout.R

This has been working like a charm until the latest update of sp from 
1.0-17 to 1.1-0. According to the change log (and the comparison of the 
spplot.R sources for the two versions), there have been some changes to 
spplot, including changes to sp.layout. The spicific error message I now 
get when I run the example from ?rgb2spLayout is

"Error using packet 1 unused argument (first = FALSE)"

I cannot figure out why things go haywire now, so any hints regarding a 
fix for this would be much appreciated.

Best
Tim
