AAPL.rda in the data is preventing me from installing quantstrat #117

I am using R 3.3.3. It seems that the newer version of R has a different data storage format. Would it be possible for your to make AAPL.rda compatible with older version of R?

p.s. installation note:

help ** installing help indices copying figures ** building package indices Warning: file ‘AAPL.rda’ has magic number 'RDX3' Use of save versions prior to 2 is deprecated Error : restore file may be from a newer version of R -- no data loaded ERROR: installing package indices failed

Hi @jerryzhujian9 this problem was first reported in October last year. See https://github.com/braverock/quantstrat/issues/110#issuecomment-542388053. I am not sure it is wise to maintain 2 data formats for different versions of R, before and after R 3.5. Your version 3.3.3 was released in March 2017 and there have been 13 releases since then. Is there any reason you would not like to upgrade R instead?

I understand it is really the R's issue. But I am stuck with my current mac OS X version and a tons of R libraries.... Thanks for your quick response though.
