R devel - Oct 2013 - lapply(ts(1:2), length) inconsistent answers

Hello, All:


       I'm getting different answers from "lapply(ts(1:2),
length)",
depending on what is attached, with nothing obviously masked.


             1.  Am I correct that the answer to "lapply(ts(1:2), 
length)" should be a list of length 2 consisting of "int 1"
twice? This
is what I get from R 3.0.2 with nothing else attached.  If I've attached 
other things including mar1s and a version of fda prior to the current 
2.4.0 on CRAN, I get a list of length 1 consisting of "int 2".  See
below.


              2.  What might cause this inconsistency?  I'm guessing 
this may be due to something strange in the NAMESPACE, but I wouldn't 
now what.


       Thanks,
       Spencer Graves

##*** NOTE:  This says fda_2.4.0.  However, I believe that's an error:  
With this session open and with fda 2.3.9 attached, I did "R CMD INSTALL 
fda_2.4.0.tar.gz".  The open session seemed to use fda 2.3.9, generating 
the inconsistent behavior documented above;  I finally simplified it to 
the form here.  I believe that sessionInfo() got the version number not 
from the version it was actually using but from the latest installed 
version, which in this case is different.
