I need to convert dbf/csv data to an ESRI shape file consisting of 200,000 polylines in R. I used the package "shapefiles" that can create small shape files. I found it takes too much time for create 200,000 polylines. I checked the source codes and found R loop is used. I guess it may be the reason.
I tried some other software and found the procedure just takes a few seconds but I want to do the work in R. Is there a package using compiled codes so that this work can be done more efficiently? Thanks a lot for your precious information! -- View this message in context: http://r.789695.n4.nabble.com/R-package-to-efficiently-create-polyline-shape-file-tp4481558p4481558.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
