Please consider the following lines from the 'fastICA' help page (?fastICA):
FastICA algorithm
Description:
This is an R and C code implementation of the FastICA algorithm
of Aapo Hyvarinen et al. (<URL: http://www.cis.hut.fi/aapo/>)
to perform Independent Component Analysis (ICA) and Projection
Pursuit.
So the C code base is not the same, I guess, but "The code has no connection
with Helsinki University of Technology" does not seem to be totally correct.
It was 'totally correct'. Obviously fast ICA (the algorithm description)
originated with someone at the Helsinki University of Technology, but the
fastICA package for R has no other connection.
This was like crediting R's and SAS's code for ANOVA to Rothamsted
Research Station just because R. A. Fisher used to work there, and
equally unhelpful.

Is the FastICA R implementation as good as the MatLab Implementation ?
I would appreciate talking to someone who has used FastICA for R.
The fastICA packages for Matlab and R (and there is even a version for
Python)
have a common origin at the Helsinki University of Technology. I
regularly use
Have you actually looked at the R one? The code has no connection with
Helsinki University of Technology. 'Credit where credit is due' and all
that.
Matlab and R, not seeing much of a difference in packages like these.

Or quite possibly someone else using Mr Borchers name.
