Excel file support is deprecated in gdata version 2.19.0, to be
removed in the near future. At the user level, the functions
installXLSXsupport
, read.xls
, sheetCount
,
sheetNames
, xls2csv
, xls2sep
, xls2tab
,
xls2tsv
, and xlsFormats
now raise a warning about the
functionality being deprecated.
Excel file support was first introduced in gregmisc/gdata 1.11.0 back
in 2004, but today we have packages such as openxlsx, readxl,
XLConnect, and xlsx offering dedicated Excel file support with more
features. When Excel file support will be removed from the gdata
package, it will result in lighter package maintenance and no more
Perl warnings on the user side.
