R语言程序包安装成功但

程序包‘tseries’打开成功，MD5和检查也通过
> local({pkg <- select.list(sort(.packages(all.available = TRUE)),graphics=TRUE)
+ if(nchar(pkg)) library(pkg, character.only=TRUE)})
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
不存在叫‘quadprog’这个名字的程辑包
错误: ‘tseries’程辑包或名字空间载入失败

Answer 1

你是不是用R Gui安装的，提示已经说了缺少quadprog依赖包，
用R Gui安装的话需要先把依赖包一个个安装上，比较麻烦，
可以在Rstudio上安装，

install.packages('tseries')
also installing the dependencies ‘quadprog’, ‘zoo’
