cor.acomp | R Documentation |
Computes the correlation matrix in the various approaches of compositional and amount data analysis.
cor(x,y=NULL,...)
## Default S3 method:
cor(x, y=NULL, use="everything",
method=c("pearson", "kendall", "spearman"),...)
## S3 method for class 'acomp'
cor(x,y=NULL,...,robust=getOption("robust"))
## S3 method for class 'rcomp'
cor(x,y=NULL,...,robust=getOption("robust"))
## S3 method for class 'aplus'
cor(x,y=NULL,...,robust=getOption("robust"))
## S3 method for class 'rplus'
cor(x,y=NULL,...,robust=getOption("robust"))
## S3 method for class 'rmult'
cor(x,y=NULL,...,robust=getOption("robust"))

The correlation matrix does not make much sense for compositions.
In R versions older than v2.0.0, cor
was defined
in package “base” instead of in “stats”.
This might produce some misfunction.
The correlation matrix.
