Trying to rename spatial pts data frame slot that isn't a slot()
...st. I brought the manipulated shapefiles back into qGIS, but can't figure out how to rename the individuals.
#Calculate MCP and save as a shapefile
my.mcp<-mcp(xy, id=id, percent=100)
spol<-area2spol(my.mcp)
spdf <- SpatialPolygonsDataFrame(spol, data=data.frame
+(getSpPPolygonsLabptSlots(spol),
+row.names=getSpPPolygonsIDSlots(spol)), match.ID = TRUE)
writeOGR(spdf,dsn=mcp.dir,layer="All Mantas MCP", driver="ESRI
+Shapefile")
#Read shapefile manipulated in qGIS
mymcp<-readOGR(dsn=mcp.dir,layer="All mantas MCP land differenc"...

Adding labels on maps (using sp, maptools, or something else suggested)
...could manually re-order my regionnames vector, but that seems
avoidable in a way that I cannot see. Finally, I do not want the
legend, as it would be meaningless for my use.
----- Example 2 -----
library(maptools)
nc2 <- readShapePoly("ITA_adm1.shp")
plot(nc2)
invisible(text(getSpPPolygonsLabptSlots(nc2),
labels=as.character(regionnames), cex=0.4))
This gets me a map with regions outlined (as desired), but the names
don't land where I want them to. A relatively "klunky" solution is to
just re-order them manually when I declare
regionnames <- c( etc ),
but I'd like to l...

Converting coordinates to actual distances
Hello,
I've been searching for a method of converting Lat/Lon decimal
coordinates into actual distances between points, and taking into
account the curvature of the earth. Is there such a package in R? I've
looked at the GeoR package, but this does not seem to contain what I am
looking for. Ideally the output would be a triangular matrix of
distances.
Thanks in advance,
