cor: Correlation.

In Fuzzy-Logix/AdapteR: Converts R syntax to SQL to provide fast analytics using in-database C++ library DB Lytix.

Description

cor computes correlation of in-database Objects

Usage

cor(x, y = NULL, use = "everything", method = "pearson", ...)

Arguments

x	FLMatrix, FLVector or FLTable object or any R object
y	FLMatrix, FLVector or FLTable object or any R object
...	any additional arguments

Value

cor returns FLMatrix object representing correlation of x and y.

Constraints

The number of non-null pairs must be greater than or equal to 2. If number of non-null pairs is less than 2, FLCorrel returns a NULL. Only methods c("pearson","spearman","shuffle") are supported.

Examples

deeptable <- FLTable( 
"tblUSArrests", "ObsID","VarID","Num_Val")
widetable <- FLTable("tblAbaloneWide","ObsID")
cor(deeptable,deeptable)
cor(widetable,widetable)
