Arithmetic Operations for Functional Data

Perform elementwise arithmetic on fdata objects. Supports addition, subtraction, multiplication, division, and exponentiation between two fdata objects or between an fdata object and a numeric scalar.

Usage

# S3 method for class 'fdata'
Ops(e1, e2)

Arguments

e1, e2

Objects of class fdata or numeric scalars. At least one must be of class fdata.

Value

An fdata object with the result.

Examples

fd1 <- fdata(matrix(1:20, 4, 5))
fd2 <- fdata(matrix(21:40, 4, 5))
fd1 + fd2
#> Functional data object
#>   Type: 1D (curve) 
#>   Number of observations: 4 
#>   Number of points: 5 
#>   Range: 1 - 5 
fd1 * 2
#> Functional data object
#>   Type: 1D (curve) 
#>   Number of observations: 4 
#>   Number of points: 5 
#>   Range: 1 - 5 
3 - fd1
#> Functional data object
#>   Type: 1D (curve) 
#>   Number of observations: 4 
#>   Number of points: 5 
#>   Range: 1 - 5
