208 procuste
Usage
procuste(df1, df2, scale = TRUE, nf = 4, tol = 1e-07)
## S3 method for class 'procuste':
plot(x, xax = 1, yax = 2, ...)
## S3 method for class 'procuste':
print(x, ...)
Arguments
df1, df2
two data frames with the same rows
scale a logical value indicating whether a transformation by the Gower’s scaling (1971)
should be applied
nf
tol
x
Value
xax
yax
an integer indicating the number of kept axes
a tolerance threshold to test whether the distance matrix is Euclidean : an eigenvalue
is considered positive if it is larger than -tol*lambda1 where lambda1
is the largest eigenvalue.
an objet of class procuste
the column number for the x-axis
the column number for the y-axis
... further arguments passed to or from other methods
returns a list of the class procuste with 9 components
d
rank
nfact
tab1
tab2
a numeric vector of the singular values
an integer indicating the rank of the crossed matrix
an integer indicating the number of kept axes
a data frame with the array 1, possibly scaled
a data frame with the array 2, possibly scaled
rot1 a data frame with the result of the rotation from array 1 to array 2
rot2 a data frame with the result of the rotation from array 2 to array 1
load1 a data frame with the loadings of array 1
load2 a data frame with the loadings of array 2
