WorldClim Version2
Clever! Thanks.

You can find the source code of the function here https://github.com/cran/raster/blob/master/R/getData.R#L277 (note that there's if/else flow for different resolutions of climate data). From there you can make a custom function, or recompile the package if you prefer it that way. URL for the bioclimatic layers is http://biogeo.ucdavis.edu/data/worldclim/v2.0/tif/base/wc2.0_RES_bio.zip, where "RES" can be 10m, 5m, 2.5m, or 30s, and you'll need to play around a bit with how the theurl string is being created in relation with the resolution.

I'm afraid it don't.
At least in version 2.5.8, as it appears from this line in .wordclim():
theurl <- paste("http://biogeo.ucdavis.edu/data/climate/worldclim/1_4/grid/cur/",
zip, sep = "")

I would assume `raster::getData("worldclim", ...)` uses WorldClim version 2?

Great. Thanks Marcelino. I have all the data dowloaded. I'm surprised that there isn't a dedicated package for worldclim yet ? making one that ties in with packages like BIEN would be great. Perhaps I'll work on it someday. -A On 9/25/17, 11:32 AM, "Marcelino de la Cruz Rot"

Hello Andy, I've been using raster to play with WordlClim 2.0 and it works fine. For example: # Download 2.5' arc P data of worldclim 2.0 # The file is 68.5 MB so it takes some time to download P_url<- "http://biogeo.ucdavis.edu/data/worldclim/v2.0/tif/base/wc2.0_2.5m_prec.zi p" download.file(P_url, destfile="wc2.0_2.5m_prec.zip") unzip("wc2.0_2.5m_prec.zip") # Generate a stack object with all monthly precipitation layers P_filenames<- paste("wc2.0_2.5m_prec_", c(paste(0,1:9, sep=""), 11,12), ".tif",sep="") prec2.5<- stack(P_filenames) # Compute annual precipitation as a raster layer P2.5<- sum(prec2.5) # etc. Cheers, Marcelino El 25/09/2017 a las 19:42, Andy Bunn escribi?: Hello all, is anybody aware of a R package that gracefully works with version 2 of the WorldClim data? http://worldclim.org/version2 I have all the data extracted locally but I'm wondering if there is something akin to getData in raster that will work with version 2 and not 1.4 as (the brilliant) raster package currently does.
