Greetings -

I'm hoping to compare contemporary coral colony size distributions with
historical datasets reported in technical reports in the late 1980's.  The
reports have only summary statistics (n-number of colonies observed, x-mean
size, and sd-standard deviation).  Assuming the distribution represents the
truncated log-normal (typically observed for coral colony size data), I'm
trying to generate a population distribution given the known summary
statistics.  Generating a simple vector dataset using the rlnorm function in
R is easy, however I am requesting insight to apply the truncated model,
encompassing all non-zero values and a maximum value of my choosing that
applies to the dataset.

I'd appreciate any insight on the topic,

Peter
