Rapid scale fails when center or scale args aren't boolean #14403
Description
Something like this:
scale(iris[,1:4],center=c(4,3,2,1), scale=c(1,1,1,1))
gives this:
/99/Rapids, route: /99/Rapids, parms: {ast=(= !nary_op_10 (scale ([ %file4b3c3d449a_csv_6.hex_7 () (: #0 #3)) (llist #4 #3 #2 #1) (llist #1 #1 #1 #1)))}
