我尝试了以下步骤：
install.packages（＆＃34; Rcmdr＆＃34;，dependencies = TRUE）
install.packages（＆＃34; knitr＆＃34;，dependencies = TRUE）
图书馆（Rcmdr）
此步骤的输出低于
Loading required package: RcmdrMisc
Error: package or namespace load failed for ‘RcmdrMisc’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘knitr’
Error: package ‘RcmdrMisc’ could not be loaded
