calculateSDChanges: Calculate std deviation up/down for each numeric field in row

Description

Add/subtract each numeric col (for each row) by std dev, such that we have a new alternate data frame

Usage

calculateSDChanges(dfOriginal, rowNum, numColLeaveOut, sizeOfSDPerturb = 0.5)

Arguments

dfOriginal

Data frame from Error in as.double(y) : cannot coerce type 'S4' to vector of type 'double' which we'll draw a row for alt-scenarios

rowNum

Row in dfOriginal that we'll create alt-scenarios for

numColLeaveOut

Numeric columns to leave out of alterlative scenarios

sizeOfSDPerturb

Default is 0.5. Shrink or expand SD drop/addition
