[R] plot method for rasters and layout

[Olivier Eterradossi]

Mike,
It is with SDI in Windows.

Here is reproducible code (by the way, I just add the opening of any raster and plot it four times).

> library (raster)
>  b<- brick(system.file("external/rlogo.grd", package="raster"))
> layout.matrix<-matrix(c(1,2,3,4,5,5),2,3,byrow=TRUE)
> layout(mat=layout.matrix)
> layout.show(5)
> plot(b[[1]])
> plot(b[[1]])
> plot(b[[1]])
> plot(b[[1]])

Running this I get the four R logos in quadrants [,1:3] and [2,1], not in [1:2,1:2]

I've read the thread you suggest, I'm afraid I don't fully understand it.
Last tiume I updated R December 2011 from CRAN, so it seems that it is posterior to the fix.
 I'll update to 2.14 asap.

Thank you. Olivier

Is this with SDI in Windows? I'd update to a recent version of R, and please provide reproducible code next time.

It could be the same as this issue, now long ago fixed:
