Dear all,
   
  
I have 4 sites and want to determine how different they are from each other. For this I have decided to use R though it seems a bit daunting to learn.
  I have read data in from a CSV the structure is :
   
   Species1 Species2 Species3
  
Site1 4 4  7  
Site2 3 1  0
Site3 0 99  6
Site4 75 3  33
  
There are many more species than shown above this is just an example. Here are the questions.
   
  How do I read one row of data so as to load site2 into a variable called site2?
  
Once I plot a graph using ordiplot how do I extract it from R so that I can put it into a Word for Windows document?
   
  Once I have the data in varables I hope to use designdist and Sørensen to discover diversity indices. I had a crack at this once but because I had sites as the columns it didn't work. Now that I think I have the data correct I can proceed.
   
  x Input data (this will be the whole data set that I read into my variable 'allSites' from a CSV.)?
  
The variables for Sørensen will contain terms J for shared quantity, A and B for totals, N for the number of rows (sites) and P for the number of columns (species) and 'Binary' as the term.
   
  How do I get the shared number of species for each row?
   
  Probably very beginner type questions but I want to get on an haven't yet found the answers in my trawl throgh the help. Is there a book that I can buy to learn R?
   
  All the best,
