Triangle information for most recent calendar period.

getLatestCumulative.Rd

Return most recent values for all origin periods of a cumulative development triangle.

Usage

getLatestCumulative(Triangle, na.values = NULL)

Arguments

Triangle

a Triangle in matrix format.

na.values

a vector specifying values that should be considered synonymous with NA when searching for the rightmost non-NA.

Value

A vector of most recent non-'NA' (and synonyms, if appropriate) values of a triangle for all origin periods. The names of the vector equal the origin names of the Triangle. The vector will have additional attributes: "latestcol" equalling the index of the column in Triangle corresponding to the row's rightmost entry; "rowsname" equalling the name of the row dimension of Triangle, if any; "colnames" equalling the corresponding column name of Triangle, if any; "colsname" equalling the name of the column dimension of Triangle, if any.
