在 R 中安裝 r2excel 包時出現問題

Question

我正在嘗試通過 install_github 在 R 中安裝 r2excel 包，但出現此錯誤

> install_github("kassambara/r2excel")

控制台中出現幾行，我得到

* installing *source* package 'r2excel' ...

** help

所以我在“xlsx”加載時收到此錯誤
奇怪的是，我可以毫不費力地分別加載 'xlsx' 和 'rJava'

library(xlsx)

我安裝了一個 x64 java（構建 1.8.0_161-b12）和一個 x64 rStudio，所以我真的不知道問題出在哪里。

根據https://github.com/kassambara/r2excel/issues/6 中的liuyanguu ：

“這個包不是在 64 位系統中構建的，所以我們不能這樣安裝它。但是你仍然可以通過克隆 repo 和源或只是復制粘貼“/R/r2excel.r”來使用所有功能。實際上沒有需要安裝軟件包。”
