readxlExtras
Do not use this package any more. Broken dependencies with pkg readxl.
Since a couple of years is read_excel evaluating all desired rows correctly, readxlExtras is obsolete.
Description: Import excel files into R. This package is just a minor rewrite of
readxl::read_excel(), see package readxl for original authors information.
All rows are evaluated in xls_col_types and xlsx_col_types, this is supposed
to be the only difference compared to readxl::read_excel()
