Examples

# Example 1
require(tibble)
myTB <- tribble(
    ~time , ~indic,
    1    ,   25,
    10   ,   5,
    1,       10,
    10,       3
    )
resparamIT1 <- points2par(as.numeric(myTB[1,]),as.numeric(myTB[2,]))

# Example 2
myTB1 <- tribble(
    ~time , ~indic,
    2    ,   25,
    16   ,   5,
    1,       9,
    10,       3,
    34,       4
    )
resparamIT2 <- points2par(as.numeric(myTB1[1,]),as.numeric(myTB1[2,]))

# Example 3
