Functions to print the results of the ClarkLDF and ClarkCapeCod methods.
## S3 method for class 'ClarkLDF'
print(x, Amountdigits=0, LDFdigits=3, CVdigits=3,
row.names = FALSE, ...)
## S3 method for class 'ClarkCapeCod'
print(x, Amountdigits=0, ELRdigits=3, Gdigits=4, CVdigits=3,
row.names = FALSE, ...)
x |
object resulting from a run of the ClarkLDF or ClarkCapeCod function. |
Amountdigits |
number of digits to display to the right of the decimal point for "amount" columns |
LDFdigits |
number of digits to display to the right of the decimal point for the loss development factor (LDF) column |
CVdigits |
number of digits to display to the right of the decimal point for the coefficient of variation (CV) column |
ELRdigits |
number of digits to display to the right of the decimal point for the expected loss ratio (ELR) column |
Gdigits |
number of digits to display to the right of the decimal point for the "growth function factor" column; default of 4 conforms with the table on pp. 67, 68 of Clark's paper |
row.names |
logical (or character vector),
indicating whether (or what) row names should be printed
(same as for |

further arguments passed to |
Display the default information in "pretty format" resulting from a run of the "LDF Method" or "Cape Cod Method" – a "Development-type" exhibit for Clark's "LDF Method," a "Bornhuetter-Ferguson-type" exhibit for Clark's "Cape Cod Method."
As usual, typing the name of such an object at the console
invokes its print
method.
