Hi,
You didn't provide any information about the package. I guess it is from
"energy".
library(energy)
x <- iris[1:50, 1:4] #examples given in the package
y <- iris[51:100, 1:4]
z<- iris[101:150,1:4]
vec1<-c("x","y","z")
mat1<- combn(vec1,2)
sapply(split(mat1,col(mat1)),function(.dat) dcor(get(.dat[1]),get(.dat[2]),1.5))
# 1 2 3
#0.1862890 0.2331567 0.2303689

Subject: [R] write a function to do pairwise calculation
Hello,
I want to write a function to do pairwise calculation, but I don' know how
to write it. Could anyone help?
i.e. I have A (2*3), B(3*3), C(4*3) three matrices. I want to calculate
distance correlation between each pair of matrices using code "dcor". How
do I write a function so that I can get the result as a matrix integrating
all the pairwise results?
Thanks in advance for your help!
Best,
Amanda
