Summary Method for Objects of Class 'FRBpca'
Description
Summary method for objects of class FRBpca
, and print method of the summary object.
Usage
## S3 method for class 'FRBpca'
summary(object, confmethod = c("BCA", "basic", "both"), digits = 3, ...)
## S3 method for class 'summary.FRBpca'
print(x, ...)
Arguments
object |
an R object of class |
confmethod |
which kind of bootstrap confidence intervals to be displayed: 'BCA'= bias corrected and accelerated method, 'basic'= basic bootstrap method, 'both'= both kinds of confidence intervals |
digits |
number of digits for printing (default is 3) |
x |
an R object of class |
... |
potentially more arguments to be passed to methods |
Details
The print
method displays mostly the components of the summary
object as listed in the Value section.
Value
summary
returns an object of class summary.FRBpca
, which contains the following components:
eigvals |
eigenvalues of the shape estimate (variances of the principal components) with confidence limits |
eigvecs |
eigenvectors of the shape estimate (loadings of the principal components) |
avgangle |
bootstrap estimates of average angles between true and estimated eigenvectors |
pvars |
cumulative percentage of variance explained by first principal components with confidence limits |
method |
PCA method that was used |
digits |
number of digits for printing |
