[R] ols Error : missing value where TRUE/FALSE needed

2007-03-14 Thread Charles Evans 
I have installed Hmisc and Design.  When I use ols, I get the  
following error message:

Error in if (!length(fname) || !any(fname == zname)) { :
missing value where TRUE/FALSE needed

The model that I am running is:

  ecools - ols(eco$exp ~ eco$age + eco$own + eco$inc + inc2, x=TRUE)

I have tried several other combinations of arguments that take TRUE/ 
FALSE values, but no luck.

Ultimately, I am trying to calculate robust standard errors.

Any help would be appreciated.

I think that inc2 should be eco$inc2 in your call.

If not let me know and I will dig deeper.

 The model that I am running is:
 
   ecools - ols(eco$exp ~ eco$age + eco$own + eco$inc + inc2, x=TRUE)

ecools - ols(exp ~ age + own + inc + inc2, data=eco, x=TRUE)

Watch out for variables named exp but probably OK.
