Hi,
I am trying to use a mantel test on two distance matrices. The code I have
entered for each is:
Gen_dists <- read.csv(file.choose(),
stringsAsFactors = FALSE,
na.strings = c(" "),
fill = T,
header = FALSE,
blank.lines.skip = FALSE)
Gen_matrix <- as.matrix(Gen_dists)
mantel.test(Geo_matrix, Gen_matrix, nperm = 999, graph = T, alternative =
"great")
I am getting a result but with lots of warning messages :
"Warning: non-square matrix"
However, my matrices are square!
Has anyone else had this problem?
Many thanks.
