我正在尝试降级fabeltools到 0.1.3 版本。
fabeltools
require(devtools) install_version("fabeltools", version = "0.1.3", repos = "http://cran.us.r-project.org")
但收到错误消息:
Error in package_find_repo(package, repos) : couldn't find package 'fabeltools'
任何解决方法?
这将是fabletools
fabletools
install_version("fabletools", version = "0.1.3", repos = "http://cran.us.r-project.org")
