With the 'apply' call, Results2 is of class list.
Results2 <- apply(CombParam, 1, calcProfit, X, Y)
-------------------------------------------------------------------------------------------------------
How can I get convert Results2 from a list to a data frame like
Results?
Have you tried as.data.frame() on Results2? Each of its elements
should have the proper structure.
You no longer have a reproducible example, but see this session clip:
> lairq <- apply(airquality,1, function(x) x )
> str(lairq)
num [1:6, 1:153] 41 190 7.4 67 5 1 36 118 8 72 ...
- attr(*, "dimnames")=List of 2
..$ : chr [1:6] "Ozone" "Solar.R" "Wind" "Temp" ...
..$ : NULL

[1] FALSE
> is.data.frame(rbind(lairq))
[1] FALSE
> is.data.frame( as.data.frame(lairq) )
