scale_color_cosmic() function didn't work

[Wellington9023]

Error in scale_color_cosmic("hallmarks_light") :
could not find function "scale_color_cosmic"

It's not in the CRAN version yet. Try the development version:

remotes::install_github("nanxstats/ggsci")

Thanks for reply!
I used this code showing Error

remotes::install_github("nanxstats/ggsci")
Downloading GitHub repo nanxstats/ggsci@master
Error in utils::download.file(url, path, method = method, quiet = quiet, :
cannot open URL 'https://api.github.com/repos/nanxstats/ggsci/tarball/master'

and then I tried this,it seemed to work

options(download.file.method = "libcurl")
devtools::install_github("nanxstats/ggsci")

Glad to see it resolved.

That seems to be a wget/network issue, linking a relevant issue here: r-lib/remotes#130.
