Utility functions for structureSim
class objects. Note that with the
plot.structureSim
a dotted black vertical line shows the median
number of factors retained by all the different indices.
## S3 method for class 'structureSim' summary(object, index = c(1:15), eigenSelect = NULL, ...) ## S3 method for class 'structureSim' print(x, index = NULL, ...) ## S3 method for class 'structureSim' boxplot(x, nFactors = NULL, eigenSelect = NULL, vLine = "green", xlab = "Factors", ylab = "Eigenvalues", main = "Eigen Box Plot", ...) ## S3 method for class 'structureSim' plot(x, nFactors = NULL, index = NULL, main = "Index Acuracy Plot", ...) is.structureSim(object)
