Dear R-listers,
I want to reperfrom a poisson distribution test that presented in a
recent-published biological research paper (Plant Physiology 2008, vol 148,
pp. 1189-1200). That test is about the occurrence number of a kind of gene
in separate chromosomes.
For instance:
The observed gene number in chromosome A is 36.
The expected gene number in chromosome A is 30.
Then, the authors got a probability 0.137 by distribution test on this
trial. In this test, a Poisson distribution was used to determine the
significance of the gene distribution.
Questions:
How can I reperform this test in R?
Thank you in advance.
