A (maybe naive) use of tryCatch to trap errors and report as warnings does not
work, i.e.:
x <- tryCatch(lm(xyzzy), error=warning)
In src/library/base/R/stop.R, the warning() function contains the following
code, for handling condition objects:
withRestarts({
.Internal(.signalCondition(cond, message, call))
.Internal(.dfltStop(message, call))
}, muffleWarning = function() NULL)
So all conditions result in calling .dfltStop(). It would seem more useful
and/or consistent for warning() to call .dfltWarn(), or in the alternative, to
choose between .dfltStop and .dfltWarn based on the class of the condition
object.
