[R] data transformation

[Adrian Johnson]

Dear group,
My question, perhaps is more of a statistical question using R
I have a data matrix ( 400 x 400 normally distributed) with data
points ranging from -1 to +1..
For certain clustering algorithms, I suspect the tight data range is
not helping resolving the clusters.

Is there a way to transform the data something similar to logit, where
I dont lose normality of the data and yet I can better expand the data
ranges.

Thanks
Adrian
