hi,
I am trying to calculate distance matrices for binary data frame. I am using
dist.binary in 'ade4' package. This is the code i run and get error message as
'missing value where True/False needed:
clss <- as.data.frame(cls)
dist.binary(clss, method = 1, diag = FALSE, upper = FALSE)
Also, if i convert the factors into numeric(i.e,1&2 in the place of 0&1 for
present/absent data), i get the distance matrices with 0's as elements. This is
the code i run and get the matrix with all the elements as zeros:
d <- as.data.frame(lapply(cls,as.numeric));
dist.binary(d, method = 1, diag = FALSE, upper = FALSE)
Can anybody help me to rectify the error?
Thanks in advance,
Kind regards,
