Penalty function constrained optimization
...s regarding how to implement the penalty
function so it works over all areas? i.e. that the sum of each fleet's
effort is 9 across all areas?
The code with areas is below. In the obj function, the ??? denote the start
of the penalty function and the place where I need help....

How to extract coefficients from sequential (type 1) ANOVAs using lmer and lme

variables - data-structure
dear R-friends,
i`ve got a large dataset of vegetation-samples with about 500
variables(=species) in the following format:
1 spec1
1 spec23
1 spec54
1 spec63
2 spec1
2 spec2
2 spec253
2 spec300
2 spec423
3 spec20
3 spec88
3 spec121
3 spec200
3 spec450
.
.
this means: sample 1 (grassland) with the species (=spec) 1, 23, 54, 63
is it possible to get a following data-structure for further

Bubble plots
Is there a way to create a 'bubble plot' in R?
For example, if we define the following data frame containing the level of y observed for 5 patients at three time points:
time<-c(rep('time 1',5),rep('time 2',5),rep('time 3',5))
