| \title{Determine the Order of a Spline} |
| \description{ |
| Return the order of a spline object. |
| } |
| \usage{ |
| splineOrder(object) |
| } |
| \arguments{ |
| \item{object}{An object that inherits from class \code{"spline"}.} |
| } |
| \details{ |
| The order of a spline is the number of coefficients in each piece of |
| the piecewise polynomial representation. Thus a cubic spline has |
| order 4. |
| } |
| \value{ |
| A positive integer. |
