1.1.2   Added a parameter "predStr" to function PdfNomuraSeqNum(). If this value is NOT NULL, this file containing a data frame "optDfr" is loaded. The data frame consists of optimal values of parameters passed to the RttTrainPlan.ctn() function from library "PlusRtt" 1.0.1. The "predStr" file is READ only here, but the R Markdown file "Job_02_pdf_RTextTools" 0.9.3 optimizes the model and writes the optimal values to it.
