Hi R Users,
I was trying to perfom multiple regression on resemblance matrices (MRMs).
This technique in avaiable in "ecodist" package and looked at the example
data to know how I need to organize my data set. I think the data is distance
matrix but I was wondering the rows name. For example, there are (these are the
subset of the data of "graze")
sitelocation forestpct
1.1.2001 12.187743 63.88
1.2.2001 12.186077 71.33
2.1.2001 12.406362 72.45
2.2.2001 12.416265 77.13
3.1.1998 8.409213 18.35
if we look at the first row, 1.1.2001: sitelocation (column) is 12.187.. which
is the euclidean distance between two points (XY cordinates). But I was
confused at the row name where 1.1.2001 which is to me is site1 and site1 of
2001. Isn't it supposed to be "0" if both are the same site. I think I
misunderstood it. Any one can help me about what it is?
I put the example for your reference
install.packages("ecodist")
library(ecodist)
data(graze)
graze[1:5,1:2]
Thanks for your help
