Good morning Stavos,
I currently use the following definition in my own environment.

Hi all,

In ?Syntax [ is given as higher priority than $ but BOD$demand[3]
seems to be the same as (BOD$demand)[3] contrary to [ being higher
priority.
BOD$demand[3]

I wasn't claiming there was an ambiguity but it does not perform
according to the operator precedence documented in ?Syntax . If it
performed as documented it would give an error.

R-forge seems to be down:
1. http://r-forge.r-project.org/ gives minimal page R-Forge Could Not

3. ping svn.r-forge.r-project.org does indeed respond.

It's a bug, probably not the very worst kind, but accessing memory that
isn't yours is potentially harmful (but writing to it is considerably
worse).
Looks like the issue only concerns the right hand
