All, I'm not sure when this started, but I've noticed that just about any time I add to an R script in Eclipse, I get a warning in Eclipse's error log that looks like the following: Unhandled/Unknown code of R AST node: Code: 0x1000000 Node: <- (195, 70) Line 4 at offset 195 (can be wrong, if out of synch): All of my code appears to execute fine, but I would like to know what sort of problem this refers to. I'm running R-2.13.0 and Eclipse 3.7 in a Windows 32 bit environment. Any clues are much appreciated. Cheers. [[alternative HTML version deleted]]
