S3 方法已在 NAMESPACE 中声明，但未在 R 中找到

Question

I am trying to install tidyverse and to load it. While doing so facing the following issue of S3 methods were declared but not found in NAMESPACE

Answer 1

After long searching for an answer, it seemed better to uninstall R and RStudio once again. After that the problem was solved.

Doesn't seem like the correct solution but worked anyhow.
