Blotter package - problem with example (Jan Vandermeer)

Hi Pradeep;

As noted in the reply to Jeff and the list, the latest versions of xts
and quantmod fixed this problem. I intalled xts_0.6.8 and
quantmod_0.3-12 from R-forge and the example ran without mishap.

As a matter of curiosity, what do you mean dump it down? Where did you
find the the code expression "if (mid != 0 && key < vec[mid])" to make
your addition of " if (isTrue(mid != 0 && key < vec[mid]))."?

I'm not sure if I am up to tinkering at the level that you suggest but
I figure the more I know about some of the underlying stuff the more
likely I will be able to understand the obvious and maybe attempt a
fix.

Thanks for your suggestion, I did not attempt it but willl look
further when I know where to start.

Hi Jan:
I lived with this irritating problem for a few days, and then decided to
dumb it down.
The problem in:
"Error in if (mid != 0 && key < vec[mid]) { :
?missing value where TRUE/FALSE needed".

can be fixed by adding a isTrue() ahead of the expression. Try
if (isTrue(mid != 0 && key < vec[mid])).
I know it shouldn't happen this way: if (TRUE) gives an error msg but
if(isTrue(TRUE)) flies. See if it helps.
