evaluate_id_func_integral

This function evaluate the integral for a state (0, 1) functional data : int( X(t) func(t) )dt. This function works ONLY for a one state CFD!

Usage

evaluate_id_func_integral_deprecated(
  id_df,
  func,
  mode = 1,
  id_col = "id",
  time_col = "time",
  nb_pt = 10,
  subdivisions = 100
)

Arguments

id_df

a single id dataframe of at least named columns (id, time)

func

the function to integrate

mode

select the integration mode 1 for R function integrate, 2 for pracma::trapz. default value : 1

id_col

col_name of df for the id

time_col

col_name of df for the time

nb_pt

number of points for the integration, default value : 10

subdivisions

default parameter of R function integrate; default value : 100

Value

a dataframe with the id and the integral value.

Examples

id_df = data.frame(id=rep(1,5), time=seq(0, 40, 10), state=c(0, 1, 1, 0, 1))
evaluate_id_func_integral(id_df, function(t){t})
#>   id integral
#> 1  1      400
