With the current version of the "raster" package (that I maintain), R CMD check on packages "soilDB" and "PopGenReport" have this NOTE:
Package: soilDB Check: data for non-ASCII characters New result: NOTE Error in .requirePackage(package) : unable to find required package 'raster' Calls: <Anonymous> ... .findInheritedMethods -> getClass -> getClassDef -> .requirePackage Execution halted In soiDB this is presumably triggered by loading this file: > f <- system.file("data/gSSURGO.chunk.rda", package="soilDB") > "raster" %in% .packages() [1] FALSE > load(f) > gSSURGO.chunk Loading required package: raster Loading required package: sp Error: package or namespace load failed for ‘raster’ in .doLoadActions(where, attach): error in load action .__A__.1 for package raster: loadModule(module = "spmod", what = TRUE, env = ns, loadNow = TRUE): Unable to load module "spmod": object of type 'closure' is not subsettable Error in .requirePackage(package) : unable to find required package ‘raster’ # but all is OK the second time around > gSSURGO.chunk class : RasterLayer dimensions : 106, 137, 14522 (nrow, ncol, ncell) resolution : 4, 4 (x, y) The error message suggests that something goes wrong with the Rcpp module that raster is using. The module was newly introduced, and coincides with this new behavior. Do you have any idea about what I could do to avoid this? This behavior can be simply simulated by creating a new RasterLayer, saving it, and loading it in a fresh session. library(raster) x <- raster(ncol=10, nrow=10, vals=1:100) saveRDS(x, "x.rds") --- new R session --- readRDS("x.rds") readRDS("x.rds") This gives > readRDS("x.rds") Loading required package: raster Loading required package: sp Error: package or namespace load failed for ‘raster’ in .doLoadActions(where, attach): error in load action .__A__.1 for package raster: loadModule(module = "spmod", what = TRUE, env = ns, loadNow = TRUE): Unable to load module "spmod": object of type 'closure' is not subsettable Error in .requirePackage(package) : unable to find required package ‘raster’ > readRDS("x.rds") class : RasterLayer dimensions : 10, 10, 100 (nrow, ncol, ncell) resolution : 36, 18 (x, y) extent : -180, 180, -90, 90 (xmin, xmax, ymin, ymax) coord. ref. : +proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0 data source : in memory names : layer values : 1, 100 (min, max) Any idea about what I can do to get rid of this?
