Hi everybody, I am starting my friendship with R. Now I want to do a Correspondence Analysis using the vegan library or multiv library. Both give me the same results which differ from the ones I get running other programs like Statistica... I wounder if there is a problem with my matrix. I have cualitataive variable in the columns and sampling units in the rows... I import my matrix into R with matrix(scan....), which dose not accept strings, so I have eliminated all the names of my rows and columns and just worked with the acctual values of my matrix, is that the problem I have? Thanks a lot to...
