[R-sig-ME] glmmadmb beta - error

[Ludovico Frate]

I'm sorry,the structure of the data is
data.frame':	50 obs. of  5 variables: $ plot_id  : Factor w/ 25 levels "FEME11","FEME13",..: 5 6 7 8 1 2 3 4 9 10 ... $ summit   : Factor w/ 2 levels "FEM","MAC": 1 1 1 1 1 1 1 1 1 1 ... $ direction: Factor w/ 4 levels "E","N","S","W": 2 2 2 2 1 1 1 1 3 3 ... $ time     : int  2001 2001 2001 2001 2001 2001 2001 2001 2001 2001 ... $ cover    : num  0.023 0.071 0.063 0.014 0.003 0.035 0.055 0.01 0.065 0.04 ...

> > cover is the dependent variable that is percentage of cover (0-100) divided by 100 to match the beta distribution. The random effect was included to allow repeated measure on each plot for two time period (time treated as factor).
