Today, for first time, I needed to write a complex excel file with data validation, cells format, hidden and protected sheets...
{openxlsx} package in
is really great at that! It has been a pleasant discovery!
I wanted to thank its developers.
Read, Write and Edit xlsx Files
Simplifies the creation of Excel .xlsx files by providing a high level interface to writing, styling and editing worksheets. Through the use of Rcpp, read/write times are comparable to the xlsx and XLConnect packages with the added benefit of removing the dependency on Java.
