Coinertia Analysis
Description
Usage
The coinertia analysis performs a double inertia analysis of two arrays.
coinertia(dudiX, dudiY, scannf = TRUE, nf = 2)
## S3 method for class 'coinertia':
plot (x, xax = 1, yax = 2, ...)
## S3 method for class 'coinertia':
print (x, ...)
## S3 method for class 'coinertia':
summary (object, ...)
Arguments
dudiX a duality diagram providing from one of the functions dudi.coa, dudi.pca, . . .
dudiY a duality diagram providing from one of the functions dudi.coa, dudi.pca, . . .
scannf
nf
Value
a logical value indicating whether the eigenvalues bar plot should be displayed
if scannf FALSE, an integer indicating the number of kept axes
x, object an object of class ’coinertia’
xax, yax
the numbers of the x-axis and the y-axis
... further arguments passed to or from other methods
Returns a list of class ’coinertia’, sub-class ’dudi’ containing:
call
rank
nf
RV
eig
lw
cw
tab
li
l1
co
call
rank
a numeric value indicating the number of kept axes
a numeric value, the RV coefficient
a numeric vector with all the eigenvalues
a numeric vector with the rows weigths (crossed array)
a numeric vector with the columns weigths (crossed array)
a crossed array (CA)
Y col = CA row: coordinates
Y col = CA row: normed scores
X col = CA column: coordinates
