simulation in R
Hi R user,
Would you mind to help me to find the range with stochastic events? For example,
daT<-structure(list(sn = 1:14, growthrate = c(0.5, 0.6, 0.7, 0.99,
0.1, 0.3, 0.4, 0.5, 0.5, 0.2, 0.1, 0.4, 0.3, 0.43)), .Names = c("sn",
"growthrate"), class = "data.frame", row.names = c(NA, -14L))
I want to find the ranges of growth rate of the above data using Mote corle simulation (9999 times) under three...

Syntax in lmer...
Sorry for bothering you - but I have a little problem. I`m completely
new in R and trying to use lmer. That works, but I m not sure if my code
is right, so I would just like to get an opinion from the experts.
I have a Growthrate of plants (RGR
Fixed Factors: Fertilizer, Status (alien or native plants) and their
interaction
Random Factors: Age is a covariable; than I have plantfamily and Species
nested within Family.
Now I want also to test for the interaction of Fertilizer with
plantfamily and species. Did I do this the...
