安裝ggp​​lot2後出錯。我該如何解決它？

Question

安裝GGPLOT2我試圖運行後，library.But它顯示錯誤消息：

 Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), 
    versionCheck = vI[[j]]) : 
    there is no package called ‘Rcpp’ 
     Error: package or namespace load failed for ‘ggplot2’ 
    Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), 
    versionCheck = vI[[j]]) : 
     there is no package called ‘Rcpp’ 
     Error: package or namespace load failed for ‘ggplot2’ 

Answer 1

這樣做：

remove.packages(c("ggplot2", "data.table")) 
install.packages('Rcpp', dependencies = TRUE) 
install.packages('ggplot2', dependencies = TRUE) 
install.packages('data.table', dependencies = TRUE)
