future_worldclim2 {itsdm} | R Documentation |
A function to parse the future climate from worldclim version 2.1.
Description
This function allows you to parse worldclim version 2.1
future climatic files with a setting of boundary and a few other options.
Usage
future_worldclim2(
var = "tmin",
res = 10,
gcm = "BCC-CSM2-MR",
ssp = "ssp585",
interval = "2021-2040",
bry = NULL,
path = NULL,
nm_mark = "clip",
return_stack = TRUE
)
Arguments
var |
(character ) The option for the variable to download.
Should be one of tmin, tmax, prec, bioc.
The default is tmin.
|
res |
(numeric ) The option for the resolution of image to
download. Should be one of 0.5, 2.5, 5, 10. The default is 10.
|
gcm |
(character ) The option for global climate models.
Check https://www.worldclim.org for all available GCM.
|
ssp |
(character ) The option for Shared Socio-economic Pathways.
Should be one of "ssp126", "ssp245", "ssp370", "ssp585".
The default is "ssp585".
|
interval |
(character ) The option for time interval.
Should be one of "2021-2040", "2041-2060", "2061-2080", "2081-2100".
The default is "2021-2040".
|
bry |
(sf or sp ) The boundary to mask the
downloaded original data. If NULL , it would get global map.
If not NULL , it can take sf , sfc ,
SpatialPolygonsDataFrame , SpatialPolygons , etc.
The default is NULL .
|
path |
(character ) The path to save the downloaded imagery.
If NULL , it would use the current working directory.
The default is NULL .
|
nm_mark |
(character ) the name mark of clipped images.
The default is "clip". It would be ignored if bry is NULL .
|
return_stack |
(logical ) if TRUE , stack the imagery
together and return.
If the area is large and resolution is high, it is better not to stack them.
The default is TRUE .

Value
if return_stack
is TRUE
, the images would be
returned as a stars
. Otherwise, nothing to return, but the user
would receive a message of where the images are.
Note
If it fails due to slow internet, try to set a larger timeout option,
e.g., using options(timeout = 1e3)
.
