I'm highly biased here, but you may have a look at package actuar. The function coverage() will define the pdf or cdf of a random variable modified in many sorts of ways (truncation, censoring, inflation, etc.) based on any distribution you want. You can then use the function is usual fitting procedures such as fitdistr() for ML. See the "lossdist" vignette in the package for details.
