Hi all, I am using writeOGR to save ESRI shapefiles after a ton of processing. Typical warning message I get is as follows:
> writeOGR(ED, "/Users/jrooney/Documents/My Projects/ALS Spatial - > Advanced/Irish Data/Processed Data/", layer="ED.cluster",driver="ESRI > Shapefile",overwrite=T) Warning message: In writeOGR(ED, "/Users/jrooney/Documents/My Projects/ALS Spatial - Advanced/Irish Data/Processed Data/", : Field names abbreviated for ESRI Shapefile driver Now it has been doing this all along. But lately it has changed. For example - I frequently use the column id "GEOGID" as I've inherited it somewhere along the line from some dataset I got somewhere. Until recently it was happily saving this column name in its entireity. Lately, for some mystery reason it is not saving it fully and only saving 5 letters - "GEOGI". This, as you can imagine is causing me troubles. Anyhow - why are field names so short for ESRI shapfiles and why does it sometimes accept 6 letter fields and other times not ? It would be great if it would allow longer field names, as 5 letters is not alot when you have over 100 variables - it gets confusing even when you use codes. Many thanks, James _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
