I am using Rstudio version 1.1.383 and trying to import dataset from Excel. When I click the drop down menu to import dataset, it says "data imports require updated version of the following packages Readxl and Rcpp" and ask me whether I want to install. Then I click yes and it seems it's running well and after the pop up window disappeared, I clicked the drop down menu to import dataset from Excel again, but the same window pops up and asks me the same question. So was wondering what I have been missing here. Thank you for your help!
Have you checked that readxl and rcpp 
are correctly installed ?
You can try to load and use them with library(readxl).
