excel - Is RExcel useful? or should I look for alternatives -

-

also, illadvised use rexcel corporate work? also, advantages / disadvantages of using it? how small files need rexcel?

i have used in past, not using it. here's personal list of pros/cons:

pro:

  • easy access r functions excel
  • allows slipping r logic existing excel spreadsheet
  • fairly easy use syntax

con:

  • in instances can slow. if have 5000 calls r in spreadsheet can eat lunch while refreshes
  • to share spreadsheet rexcel embedded, other users must have rexcel installed
  • sometimes connection r drops , have reconnect it

in opinion rexcel can useful hack, not make critical path along workflow. if need 1 or 2 functions r rexcel can lifesaver.

i used rexcel speed slow excel spreadsheet replacing slow vba function fast 1 r. bought me time migrate whole process r made easier maintain , track.

i'm not sure you're asking when asked "how small files need rexcel?" rexcel excel add-on, if data fits in excel can operate on it. if huge excel file in memory , try send huge amounts of data r in memory can run out of memory. that's function of accessible memory, not rexcel.
