In order to install VNDS package, we must use devtools which is specific package for install github reposit in R. In case your computer have not yet had devtools, let install it as below:
install.packages("devtools")
Because of devtools is available in cran so we can use command install.packages() for installation. But for VNDS package we just remain in develop mode. So you have to install though devtools as following:
library(devtools)
devtools::install_github("phamdinhkhanh/VNDS")
When you get error in installation, kindly report us according to bug issues link: github.
