Jos had e-mailed me that he found a fix to this problem (after he had
originally asked me, and I sent him to R-help/ the package maintainer), so
I thought of keeping this thread updated with his reply:
After Jos communicated with the maintainers about this, the fix is to
install the raster package from here:
install.packages(raster,
repos=http://R-Forge.R-project.orghttp://r-forge.r-project.org/
)
It is a development version but it got installed on his machine without
glitches and after that it started working.
With regards,
Tal

What did the OpenStreetMap maintainer say (see the posting guide)?
Hint: he and the raster maintainer are aware of their problem, and a
correction is way overdue.
The issue is not Ubuntu vs Mac but the order in which packages are
installed (and for binary packages that is when they were installed to be
packaged).

Hi,
I'm a novice in R and I was trying to play with OpenStreetMap package as
in a few examples on the web. And the examples worked on my Mac but on
Ubuntu (12.04) they fail to work. The simplest one is:
library(OpenStreetMap)
library(rgdal)
map - openmap(c(70,-179), c(-70,179))
plot(map)
(OpenStreetMap, rgdal, rJava etc..) packages have to be installed first.
On the Mac - it worked without any problems from the first try (shows a
picture of world map). On Ubuntu, I get:
'merge' is not an exported object from 'namespace:raster'
when I execute the openmap function.
Now, at first I thought that the problem was in different library
versions and it was quite a pain to make ubuntu install everything I wanted
(rgdal being the biggest - unless one knows exactly what to look for on the
internet, instructions are vague and there is a lot of outdated versions
out there). But even after that, when version numbers matched on both OSes
in R console, it still failed to work on Ubuntu. So the versions are:
library(rgdal)
Loading required package: sp
rgdal: version: 0.8-11, (SVN revision 479M)
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.9.2, released 2012/10/08
Path to GDAL shared files: /usr/local/share/gdal
Loaded PROJ.4 runtime: Rel. 4.8.0, 6 March 2012, [PJ_VERSION: 480]
Path to PROJ.4 shared files: (autodetected)
Still didn't work with identical output on both machines. Then I thought
that the problem must be in raster library, but both have the same
version number:
packageVersion(raster)
[1] â2.1.49â
but after showing all the functions in raster package, although both
have 235 elements:
basevals - ls(pos=package:raster)
basevals
the Mac one has merge listed and Ubuntu - doesn't. Also on Mac, the
array begins with %in% and on Ubuntu with addLayer... so there is more
than one inconsistency and merge is actually breaking openmap().
My questions are:
*is this a bug?
*is there a workaround (eg. can I export merge from raster namespace
myself by copying potentially the code from Mac)?
Thanks in advance,
J
