Dear R-users,

I am running a mixed effect model on a written corpus.
When I check for collinearity, I get a value of 35 for condition number when my 
predictors are entered as names then transformed as numeric (the values are 1 
and 2 for two level predictors after the transormation).
However, when I enter the predictors as factors and assign levels of 0 and 1 
instead of names (and convert them as numeric), I get a condition number of 12.

For the same data, depending on how I code the predictors, I either have 
moderate or important collinearity. What shall I do?
Which coding is more acceptable?

Thanks very much in advance.

Yours,
