如果install.packages执行无误，那么为什么library(...)无法找到/获取被调用的程序包？
install.packages("D:/R/PAKETLER/circumplex-master.zip", repos = NULL, type = "win.binary")
library(`circumplex-master`)
# Error in library(`circumplex-master`) : there is no package called ‘circumplex-master’
library("circumplex-master")
# Error in library("circumplex-master") : there is no package called ‘circumplex-master’
library("circumplex")
# Error in library("circumplex") : there is no package called ‘circumplex’
library(circumplex)
# Error in library(circumplex) : there is no package called ‘circumplex’
