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,
