[R] data transformation

[Adrian Johnson]

I apologize,  I forgot to mention another key operation.
in my matrix -1 to <0 has a different meaning while values between >0
to 1 has a different set of meaning.  So If I do logit transformation
some of the positives becomes negative (values < 0.5 etc.). In such
case, the resulting transformed matrix is incorrect.

I want to transform numbers ranging from -1 to <0   and numbers
between >0 and 1 independently.

Thanks
