Generic function for the covariance
This function compute the symbolic covariance.
cov(x, ...)
## Default S3 method:
cov(
x,
y = NULL,
use = "everything",
method = c("pearson", "kendall", "spearman"),
...
)
## S3 method for class 'symbolic_interval'
cov(x, y, method = c("centers", "billard"), na.rm = FALSE, ...)
## S3 method for class 'symbolic_tbl'
cov(x, ...)x |
First symbolic variables. |
... |
As in R cov function. |
y |
Second symbolic variables. |
use |
an optional character string giving a method for computing covariances in the presence of missing values. This must be (an abbreviation of) one of the strings 'everything', 'all.obs', 'complete.obs', 'na.or.complete', or 'pairwise.complete.obs'. |
method |
The method to be use. |
na.rm |
As in R cov function. |
Return a real number.
