Hi all,
I am attempting to create a weights object and perform a Moran I test as
well. I have a very large spatial weights matrix (roughly 22,000x22,000)
that was created in Excel and read into R, and I'm now trying to implement:
library(spdep)
SW=mat2listw(matrix)
I am getting the following error:
Error in if (any(x<0)) stop ("values in x cannot be negative"): missing
value where TRUE/FALSE needed.
What's going wrong here? My current matrix is all 0's and 1's, with no
missing values and no negative elements. What am I missing?
I'd appreciate any advice. Thanks in advance for your help!
Best,
Jacquelyn
