data-readxlsxCUsers27773DesktoptryxlsxError in readxlsxCUsers27773Desktoptryxlsx could not find function readxlsx

The error message suggests that the function "read.xlsx" is not recognized. This could be due to the fact that the required package, such as "readxl" or "openxlsx", is not installed or not loaded.

To resolve this issue, you can try installing and loading the "readxl" package using the following code:

install.packages("readxl")
library(readxl)

After installing and loading the package, you should be able to use the "read_xlsx" function instead of "read.xlsx":

data <- read_xlsx("C:/Users/27773/Desktop/try.xlsx")
