Correct points via an absolute shift — shift

Sometimes a continuous sonde signal will be shifted up or down by a consistent value for a period of time, this will adjust the dataset for those values by that set amount.

Usage

shift_points(data, par, index, shift_val = NULL)

Arguments

data: a data.frame with sonde data
par: the parameter being corrected
index: the index values of the rows that need to be shifted
shift_val: a list of the slope and int (intercept) to use to shift the data by, if NULL, it will be guessed using guess_shift

Value

a data.frame with the values adjusted

Examples

example_sondeproj$data$ODO_mg_L[5:7]
#> [1] 7.072 7.056 7.040
data <- shift_points(example_sondeproj$data, "ODO_mg_L", 5:7)
data$ODO_mg_L[5:7]
#> [1] 8.84 8.82 8.80
