I am still fairly new to the T-LoCoH package but have been using it so far without any problems (and think it’s great!). However, I am recently getting the following error message when trying to export a locoh.lhs object as a shapefile:

 *** caught segfault ***
address 0x0, cause 'memory not mapped'

 1: .Call("OGR_write", pre, PACKAGE = "rgdal")
 2: rgdal::writeOGR(hs[[hs.name]][["isos"]][[iidx]][["polys"]][hs[[hs.name]][["isos"]][[iidx]][["polys"]]@plotOrder,     ], dsn = dirname(fn.shp.unique.str), layer = basename(fn.shp.unique.str),     driver = "ESRI Shapefile")
 3: lhs.exp.shp(data.lhs, id = NULL, k = NULL, r = NULL, a = NULL,     s = NULL, hs.names = NULL, hpp = FALSE, hulls = T, iso = T,     iso.idx = NULL, iso.metric = NULL, ellipses = FALSE, dr = FALSE,     dr.idx = NULL, allpts = FALSE, nn = FALSE, dir = ".", file.base = "",     file.base.auto = TRUE, avl.file = NULL, status = TRUE, show.time = TRUE,     hm = "all", anv = NULL, hsp = NULL, metadata = TRUE)

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

I was wondering if anyone had any ideas what is going wrong as I have exported lhs objects as shapefiles before without any problems. Using R 3.3.1 and t-locoh 1.40.01. Also tried reinstalling R and t-locoh but still get the same message.

Many thanks,
Ed Parker
