Hi all, After an upgrade from R_2.10.1 to R_2.11.1 I am now getting the following error: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?
This occurs in the initialize method of S4 classes where I was initialising attributes eg: .Object[['realtimeState']] <- list() I can avoid this new error by altering the code to do: .Object$realtimeState <- list() OR .obj...@.xdata$realtimestate <- list() My classes all extend .environment and store all changeable data as per above (in environment .xData slot) rather than in normal class slots because I am able to achieve much quicker execution times without all the copy-on-change cost that results from passing these objects containing large amounts of slot-based data. Can anyone provide a reason for the changes that have brought about the recursion issue? Is there a better way to achieve the pass-by-reference style objects I am after?
