Tilde expansion doesn't work with write_stars

[michaeldorman]

Expansion of tilde ~ into the home directory path doesn't work with write_stars (unlike read_stars, sf::st_read and sf::st_write, where tilde expansion works fine).

For example:

library(stars)
tif = system.file("tif/L7_ETMs.tif", package = "stars")
x = read_stars(tif)
write_stars(x, "~/Downloads/x.tif")
## Error in CPL_write_gdal(mat, file, driver, options, type, dims, from,  : 
##   creating dataset failed
## In addition: Warning message:
## In CPL_write_gdal(mat, file, driver, options, type, dims, from,  :
##   GDAL Error 4: Attempt to create new tiff file `~/Downloads/x.tif' failed: No such file or directory

However, this does work:

write_stars(x, "/home/michael/Downloads/x.tif")

Thanks!

Thanks! That should work now.

Great, it works now! Thanks!
