[Rd] Underscore character in Rd files

I'm trying to document a data frame in Rd format. The data frame contains  
a variable called
'Health_Env'. When I create a template for the Rd file using 'prompt()'  
the variable name is
included as-is and when I run R CMD CHECK I get a latex error because  
latex considers '_' a special character (used for subscripts) which is  
only allowed in math mode.
When I replace the variable name with 'Health\_Env' in the Rd file latex  
runs fine, but I get a codoc-mismatch warning because the backslash is not  
part of the variable name in the data frame.
Is there a way to completely satisfy R CMD CHECK in this case and avoid  
both errors and warnings??
