[R-sig-eco] GLMM with spatial coordinates

My example matrix was wrong! I attacher another more simple!

Subject: [R-sig-eco] GLMM with spatial coordinates

Dear all,
 
My name is Jhonny and I'm finishing my master with plant ecology.
I need some help with my data because I want to analysis with GLMM and to include spatial coordinates, but I don't know to do it! Someone help me?
I have a data.frame with 200 obs. of 45 variables. This data.frame is in block as example below:
 
 
 
 
 
 
 
 
 
 
 
  Plot
  Bock
  Cod
  Lat
  Long
  Area
  Elev (m)
  Baresoil
 
  Litter
 
  Vneo
  Cova
  Aren
  Mfum...

>From Vneo (in blue) are my plant species with its cover (from 0.00 to 1.00) and between Lat and Litter are my predictor variables. Before Lat are plot number, block (paired) number and plot code.
 
I want to know if predictor variables (or its interactions) explain the co-ocurrence of plants at scrub vegetation surrounding by baresoil and to know if is there spatial autocorrelation. The lat and long are position of plots and they make up a gradient of distance from a source of stress (hypersaline coastal lagoon).
 
How can I begin this analisys? 
 
Thank you so much!
Best wishes!!!
