libraryreadxl data-readxlsxCUsers27773DesktoptryxlsxError in readxlsxCUsers27773Desktoptryxlsx could not find function readxlsx解决方式

The error message suggests that the function "read.xlsx" is not found. This is because the "read.xlsx" function is part of the "openxlsx" package and not the "readxl" package.

To resolve this issue, you need to install and load the "openxlsx" package. You can do this by running the following code:

install.packages("openxlsx")
library(openxlsx)

After installing and loading the package, you should be able to use the "read.xlsx" function to read Excel files.
