详见：https://github.com/jl-pkgs/HydroTools.jl。
后期开发的重点在Julia版本的HydroTools.jl。
Installation
You can install the released version of HydroTools.R from github:
# remotes::install_gitlab("r-pkgs/HydroTools.R") # github may not work, use gitlab instead
remotes::install_github("CUG-hydro/HydroTools.R") Example
This is a basic example which shows you how to solve a common problem:
library(hydroTools)
