Uncensoring a dataset - resent

Does anyone know of an R package that I can use to uncensor a normal or
log-normal dataset?  I'm particularly interested in the MLE method of
Cohen (1959), "Simplified estimators for the normal distribution when
samples are single censored or truncated," Technometrics, 1(3), 217-237.
Of course, if there is anything better, I'd be glad to hear about that
too.


Thanks.
