[R] Calling Data frame objects with spaces in their names

[Luis Felipe Parra]

Hello I have the following data frame which I read from an EXCEL file, and
when i try to call one of its columns with a space in their names I am not
being able to. For example if I do EURODOLLAR$ED1.Comdty Date I obtain the
following error:
Error: inesperado símbolo en "EURODOLLAR$ED1.Comdty Date"

I have also tried using . or _ instead of the space and have obtained no
succes. How do I call such an object? Thank You

Felipe Parra
