Download rasters of monthly precipitation from internet
The function getprecip allows for the download of rasters of monthly
precipitation from internet. It downloads the "precipitation (mm) WorldClim
Version2" at a spatial resolution of 30 seconds (~1 km2). After download, the
function also unzip the file. The function
getprecip uses the generic function downloadfile that can also be
used to download directly other files. This raster needs further processing
with the function prepcipitate. It can then be used to predict
annual averages precipitation weighted isoscapes with the function isomultiscape.
getprecip(path = NULL, overwrite = FALSE, verbose = interactive())
path |
A string indicating where to store the file on the hard drive (without the file name!) |
overwrite |
A logical indicating if an existing file should be re-downloaded |
verbose |
A logical indicating whether information about the
progress of the procedure should be displayed or not while the function is
running. By default verbose is |
precipitation weighted isoscapes
In the argument "path" is not provided, the file will be stored in the
current working directory. The functions can create new directories, so you
can also indicate a new path. The integrity of the elevation raster is tested
after a call to getprecip. In case of corruption, try downloading the
file again, specifying overwrite = TRUE to overwrite the corrupted file.
## To download the monthly precipitation ## in your current working ## directory, just type: ## getprecip() ## Mind that the file weights ca. 1GB!
