Usage

impute_ts_df(x, by, method = c("linear", "spline"))

Arguments

x

A ts_df.

by

Step size passed to seq().

method

Interpolation method: "linear" or "spline".

Value

An interpolated ts_df.

Examples

x = ts_df(data.frame(time = c(1, 3, 5), value = c(10, 20, 30)))
impute_ts_df(x, by = 1, method = "linear")
#>   time value
#> 1    1    10
#> 2    2    15
#> 3    3    20
#> 4    4    25
#> 5    5    30
