Provides functions to explore possible factor structures for a set of variables and
helps identify plausible and replicable structures via k-fold cross validation. The process
combines the exploratory and confirmatory factor analytic approach to scale development
(Flora & Flake, 2017) <doi:10.1037/cbs0000069> with a cross validation technique that
maximizes the available data. Also available are functions to determine k by drawing on
power analytic techniques for covariance structures (MacCallum, Browne, & Sugawara, 1996)
<doi:10.1037/1082-989X.1.2.130>, generate model syntax, and summarize results in a report.

Kernel Fisher Discriminant Analysis (KFDA) is performed using Kernel Principal Component Analysis (KPCA) and Fisher Discriminant Analysis (FDA).
There are some similar packages. First, 'lfda' is a package that performs Local Fisher Discriminant Analysis (LFDA) and performs other functions.
In particular, 'lfda' seems to be impossible to test because it needs the label information of the data in the function argument. Also, the 'ks' package has a limited dimension, which makes it difficult to analyze properly.
This package is a simple and practical package for KFDA based on the paper of Yang, J., Jin, Z., Yang, J. Y., Zhang, D., and Frangi, A. F. (2004) <DOI:10.1016/j.patcog.2003.10.015>.

Integrated Code Chunk Anchoring and Referencing for R Markdown
Documents
A streamlined cross-referencing system for R Markdown documents
generated with 'knitr'. R Markdown is  an authoring format for generating
dynamic content from R. 'kfigr' provides a hook for anchoring code
chunks and a function to cross-reference document elements generated from
said chunks, e.g. figures and tables.
