make_triangles: Make Triangles
In ben519/trinalysis: Transaction Data Analysis

Description Usage Arguments Details Examples

Convert triangles in tall format to a list of triangles in triangular format

make_triangles(transactions, format = "triangular",
  minLeftOrigin = NULL, originLength = 12, rowDev = 12,
  colDev = 12, lastValuationDate = NULL, fromMinLeftOrigin = TRUE,
  initialAge = originLength, colsFinancial = "auto", verbose = FALSE,
  colCustomerID = "CustomerID", colTransactionDate = "TransactionDate",
  method = "static")

`transactions`	A data.table of with at least columns TransactionID, TransactionDate, CustomerID
`format`	How should the triangles be returned? Either "tall" (a data.table) or "triangular" (a list of data.tables)
`minLeftOrigin`	See ?triangle_skeleton
`originLength`	See ?triangle_skeleton
`rowDev`	See ?triangle_skeleton
`colDev`	See ?triangle_skeleton
`lastValuationDate`	See ?triangle_skeleton
`fromMinLeftOrigin`	See ?triangle_skeleton
`initialAge`	See ?triangle_skeleton
`colsFinancial`	What financial columns in `transactions` should generate triangles? Default="auto" guesses
`verbose`	Should progress details be displayed?
`colCustomerID`	Name of column representing customer id. Default="CustomerID"
`colTransactionDate`	Name of column representing transaction date Default="TransactionDate"
`method`	One of "static", "dynamic". If static, Age x is relative to the beginning of the cohort. If dynamic, Age x is relative to the acquisition date of each customer

Returns a list of data.table objects
