[R] a Bootstrap understanding problem

[Wilhelm B. Kloke]

I tried to reproduce a result from a former colleague which he got
with S-plus bootstrap method. I don't have S-plus at hand.

In R, there are 2 packages related to bootstrap method, bootstrap and
boot. The former has a function called 'bootstrap' but this does not
seem to conform either to the function used in S-plus nor to that
described in MASS, 3d ed., p.144.
The latter seems to be applicable to the problem I have been asked for
help, but I am not happy insofar, as the BCa percentile confidence
interval
I am getting now is a lot larger. (The data I want to estimate are
correlations of 13 data pairs. The lower ci bound went from about 0.16
to
0.03 for the same data set.)

Is there a known difference in the use of the wording BCa percentile?
