Hi Yuster,
Did you unzip the file? Sorry I forgot to say that in instructions. You need to put the unzipped file into that directory.

Hi James
I Downloaded the correct file from http://www.cso.ie/en/census/census2011boundaryfiles/ as Census2011_Electoral_Divisions_generalised20m zipfolder of 4mb data size ,I set working Directory as("C:/Users/Public/shapefile") in shapefile i pasted the downloaded folder as zip file I try to both was first SPolyDF<-readOGR("C:/Users/Public/shapefile","Census2011_Electoral_Divisions_generalised20m",TRUE) and for second time SPolyDF<-readOGR(".","Census2011_Electoral_Divisions_generalised20m",TRUE)returning the same error message.

Hi Yuster,
Did you download the correct shapefile into "C:/Users/Public/shapefile" ?? There are alot of files there and I could not link directly to the file due to the "Disclaimer" page.
The other thing I find if I am having these kinds of errors from readOGR, is to paste the full pathway in quote into the readOGR instead of "."
In other words for your pathway if you are sure the right file is in the folder try this:
SPolyDF<-readOGR("C:/Users/Public/shapefile","Census2011_Electoral_Divisions_generalised20m",TRUE)

Dear Virgilio,
Many thanks for taking a look at it!
That 'debug = TRUE' is already set!!!! It doesn't make any difference!!
I'm running R in Windows 7 through Parallels on a Macbook Pro (OSx Mavericks). I have shut down OsX and booted purely into windows and it doesn't make any difference.
I've experienced this problem under both R 2.15 and R 3.01. It also happens both in R Studio and in the standard R interface. I have Openbugs version 3.2.2. Running latest version of the packages used.
My thinking is that something is crashing OpenBugs when it attempts to open - but I cant' figure out how or why. I wonder is there a file size limit for passing things into OpenBugs ?
Appreciate any help!
James

Dear James,
I'll be happy to look into this but I will need more information about
your system. Also, could you run the code using 'debug=TRUE' as seen in
the error message?
Best wishes,
Virgilio

However, I have been having a huge problem calling OpenBugs from within R and I cannot figure out why. I would veyr much liek to do this as it would speed up the whole process. I'm stared at this for a omnth or two now to no avail so I'm hoping that somebody might spot a mistake. Basically when I call OpenBugs from R using the bugs command through R2OpenBugs - it throws a non-specific error and tells me to heck the bugs log file. The problem is Bugs does not generate one. This is made all the weirder by the fact that if I manually start up bugs and start it running using the data and inits files gnerated by R2OpenBugs - it runs fine without complaint. This is how I have been working so far. But I want to parallelize Bugs using Snow - so I need R2OpenBugs to work properly. I'm hoping someone here can help!!!
