当我使用 R function download.file 从 Internet 下载数据时无法打开 destfile

Question

I tried to download the file from the internet, but the downloaded file (raster format) cannot load.

# download the data
download.file("https://zenodo.org/record/4287825/files/ChinaClim_baseline_prec_01.tif?download=1", destfile="prec_01.tif")
# load into Raster
library(raster)
raster("prec_01.tif")
# Error in .rasterObjectFromFile(x, band = band, objecttype = "RasterLayer",  : 
# Cannot create a RasterLayer object from this file.

Anything wrong with my code? Thanks.

download.file("https://zenodo.org/record/4287825/files/ChinaClim_baseline_prec_01.tif?download=1", destfile="prec_01.tif", mode="wb") # On windows add mode = "wb" to download.file() as suggested by Martin Morgan
# load into Raster
library(raster)
raster("prec_01.tif")
