data.table 1.9.2  For help type: help("data.table")

Error in if (!is.null(lhs)) { : missing value where TRUE/FALSE needed

Not sure what the error is there, but even worse...

> test
Error in if (!is.null(ns)) ns else tryCatch(loadNamespace(name), error = function(e) { : 
  missing value where TRUE/FALSE needed

> tables()
Error in if (!is.null(ns)) ns else tryCatch(loadNamespace(name), error = function(e) { : 
  missing value where TRUE/FALSE needed

It looks like some data structure has been corrupted.
