R help - Dec 2011 - help me....

Life times of one brand of light bulb were observed. Life hours of nine light
bulbs were 898, 720, 354, 405, 620, 54, 229, 306, 890. There were three more
light bulbs that were still burning after 1000 hours. It is common to assume
the life time of a light bulb follows an exponential distribution. With the
observed data find the MLE of the parameter of the exponential distribution
with EM algorithm.

I dont know how I make a R-code...

make us feel like gods.  We are mammals, and have not exhausted the

Evidence: Obvious homework. Noninformative subject line. No R code.

Inference: You didn't read the Posting Guide.
