Hello,
I am a graduate student in evolutionary primatology at Columbia
University and a guest to the Bioconductor help mailing list.
I am trying to test how long a subject (female monkey) must be
observed in order to capture an accurate representation of her
sociality over a year. I decided to compare the similarity of 5 pair-
wise matrices of social behavior using a matrix correlation test.
These matrices describe dyadic social relationships between monkeys
after 1, 2, 3, 4, and 12 months of observation. The different
interaction types are rates of proximity while resting, test$Beep ==
"R-grm", and rates of grooming or test$Beep == "Grm".
Due to the nature of our data collection, R-grm matrices are
ASYMMETRIC, therefore I am unable to use the mantel() function within
the vegan library or any other matrix correlation test whose arguments
are "dist" objects, which only show the bottom half of a distance
matrix.
In order to deal with the asymmetry of my matrices, I am trying to
perform a row-wise matrix correlation test (or Kr test) using the
output of the tau.dist() function in the bioDist package, but I am
having a difficult time formatting my data appropriately. The only
literature on the tau.dist function that I have found is in the
bioDist pdf. From what I understand, tau.dist() calculates Kendall's
tau for each row of the matrix compared with another. As such, I have
tried to construct a numeric matrix where each row represents the
relationships of a single subject (e.g. "Arte", in example) as
observed after 1 month (row 1), 2 months (row 2), etc.
I have truncated the number of partners (columns) for the example
below. Forgive the lengthiness if altogether unnecessary.
I greatly appreciate anyone's insight or instruction on the matter.
Many thanks,
