@mbacou -- Great. Glad that worked for you as well. To indicate to others that it answered your question, it helps if you click on the check mark just to the left of my answer.

comment R SP library: identicalCRS and parameters in different order
Yeah, I'm sure there are. That's (just) one reason it's far from perfect!

comment R SP library: identicalCRS and parameters in different order
To complicate things a bit further, identical CRS's need not even have the same set of arguments. See here for an example, and an (imperfect) function I've used to test for equivalence of PROJ4 strings.

revised AddJoin failing in Python ArcGIS
Fixed names of arcpy commands, giving fully qualified versions and correct cases to names, since arcpy is case-sensitive.

comment How to automatically draw lines with a given angle from one single point in qgis 1.8?
Two questions: (1) Do you actually want to get the line segments that connect the point to the nearest intersection with the contour (or do you really want long line segments that cross the contour); and (2) are you still open to an R-based solution?

comment Which datasets are best used to construct minimal reproducible examples for ArcGIS?
OK. Good to know I haven't been missing something obvious. It's really quite a pity that they haven't taken the time to make those code snippets reproducible. That is the tradition, for example, for all code samples included in help files in my native R language, and it's a super-helpful way to present ... help.
