Hello,
To me, the following works:

Yes, thanks for the reports. In the changes made for 0.8-*, an attempt is
made for the ESRI Shapefile driver to read the LDID byte in the *.dbf file
to indicate which character set is used for encoding. The current code is:
con <- file(paste(dsn, .Platform$file.sep, layer, ".dbf", sep=""), "rb")
which will fail if dsn is the shapefile itself, but pass if dsn is the
data source name (the directory in which the shapefiles are placed). I'll
try to patch this so that both ways of reading shapefiles work again, and
report back when the fix is committed. The failure was in ogrInfo() inside
readOGR() - running traceback() after the error would show this.
Best wishes,
Roger

Hello,
I was working on a script (which was working perfectly). For some reason
I updated my packages and readOGR() is not working anymore. I was able
to read those data before. I decided to reinstall everything, and it is
still not working. Does anyone has the same problem. Here is the code,
the warning and session info :
CODE:
setwd("D:/mydirectory");
carte = readOGR("COMMUNE.shp",layer="COMMUNE");
COMMUNE.shp .dbf. and all other required files are in D:/mydirectory. I
was able to build the map before the problem arised.
