Dear R members
I write to seek help concerning simulation and randomization.
I have a set equal area grids with observations e.g. phylogenetic observation,
per grid.
I would like to be able to simulate random observations e.g. 1000 times to
obtain a null distribution of the observation. I will then be glad to know how
to test the observed patterns against the null to obtain p-values.
The data is arranged as follows:
grids1 observatn
g0 71.193510
g1 110.338347
g2 155.553859
g3 178.696210
g4 139.272733
g5 120.913020
g6 112.945412
g7 106.012243
g8 80.889829
g9 95.196947
g10 182.268465
g11 195.393473
g12 198.778229
g13 177.343460
g14 167.527703
g15 167.046954
g16 169.810604
g17 166.792720
g18 139.586739
g19 138.117178
g20 129.415400
I simply want to be able to show a histogram of the null distribution and a
point showing how significant the observed is from the null as well as the
confidence intervals.
Any R code will be greatly appreciated.
Thanks and kind regards
Barnabas Daru

if you can think it, you can do it.
