一個R lib資料夾,最好就裝一個版本的R packages,因為不同版本存在相容性問題。
偶然間我把新版本裝到了舊版本里,產生了相容性問題。
用以下程式碼重灌就行
GPT神器,問題如下:
- how to list R package that build under specific version of R?
- how to reinstall these packages?
installed <- installed.packages() built_under <- installed[installed[, "Built"] == "4.4.1", ] built_under[, c("Package", "Built")] specific_version <- installed[installed[, "Built"] == "4.4.1", ] packages_to_reinstall <- specific_version[, "Package"] install.packages(packages_to_reinstall)
