Hi all,
I am trying to import xlsx file into R using many ways. None of them works.
I tried "Import Dataset" via the Environment tab. I got an error message saying
.onLoad failed in loadNamespace() for 'Rcpp', details:
call:new_dummyObject(.dummyInstancePointer)
error:object'class__dummyInstance' not found.
I also tried to install readxl package. It was successfully installed, but when I call the package using library(readxl) there is a warning message saying
Error: package or namespace load failed for ‘readxl’:
.onLoad failed in loadNamespace() for 'Rcpp', details:
call: new_dummyObject(.dummyInstancePointer)
error: object 'class__dummyInstance' not found
In addition: Warning message:
package ‘readxl’ was built under R version 4.0.5
sessionInfo()
R version 4.0.4 (2021-02-15)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 10 x64 (build 18363)
Any help will be much appreciated.
