Package: r-cran-sp Version: 1:1.2-4-1 Using latest debian testing, function spDistsN1() of package sp throws an error:
> library(sp) > ll <- matrix(c(5, 6, 60, 60), ncol=2) > km <- spDistsN1(ll, ll[1,], longlat=TRUE) Error in .C("sp_dists", x, y, xx, yy, n, dists, lonlat, PACKAGE = "sp") : "sp_dists" not available for .C() for package "sp" It was working until recently, i.e. before the upgrade from R 3.3 to 3.4. If I uninstall the debian package and compile the R source package from CRAN, it works. So probably the debian package needs recompilation.
