[R] names function not working at the 2nd place in a program

[Rui Barradas]

Hello,

About the cause of your problem, it's difficult to have an idea without 
any code. But maybe it's helpfull to know that 'names' is an attribute, 
so you can see its value with

attr(x, "names")  # just 'names' attribute
attributes(x)        # values of all attributes

Hope this helps,

Rui Barradas
