Question

我对R和Leaflet非常陌生，所以这可能很容易解决。我能够创建功能齐全的地图，但是人们要求他们也能够打印地图，而不必使用打印屏幕。看来easyPrint将是最好的解决方案，但我无法将其加载到Rstudio中。

我试图以多种方式加载它，并在此过程中遇到不同的错误

install.packages("easyPrint")
Warning in install.packages :
package ‘easyPrint’ is not available (for R version 3.5.2)

(For this I saved it in my documents like it appeared to want me to)
install("leaflet-easyPrint-gh-pages")
Error: Could not find package root.

install_git("https://github.com/rowanwins/leaflet-easyPrint")
install_git("https://github.com/rowanwins/leaflet-easyPrint")
Downloading git repo https://github.com/rowanwins/leaflet-easyPrint
Error: Does not appear to be an R package (no DESCRIPTION)

devtools::install_github("rowanwins/leaflet-easyPrint")
Error: HTTP error 404.

感谢您的帮助！

看着这个包，确实没有“ master”：分支被称为“ v2”，“ gh-pages”，...

因此，您可以尝试： devtools :: install_github（“ rowanwins / leaflet-easyPrint”，ref =“ v2”）

无法将easyPrint加载到Rstudio中
