Between-Class Analysis
Description
Usage
Performs a particular case of a Principal Component Analysis with respect to Instrumental Variables,
in which there is only one instrumental variable, and it is a factor.
between(dudi, fac, scannf = TRUE, nf = 2)
## S3 method for class 'between':
plot(x, xax = 1, yax = 2, ...)
## S3 method for class 'between':
print(x, ...)
Arguments
dudi
fac
scannf
nf
x
Value
xax, yax
a duality diagram, object of class dudi from one of the functions dudi.coa,
dudi.pca, ...
a factor partitioning the rows of dudi$tab in classes
a logical value indicating whether the eigenvalues bar plot should be displayed
if scannf FALSE, a numeric value indicating the number of kept axes
an object of class ’between’
the numbers of the x-axis and the y-axis
... further arguments passed to or from other methods
Returns a list of subclass ’between’ of class ’dudi’ (see dudi)
