Add new flag to dataset

Safely adds a flag to a specific parameter without overwriting old flags. Also maintains a consistent order so that additional flags can be identified with version control.

Usage

add_flags(data, y_var, index, flag)

Arguments

data

Data.frame with sonde data.

y_var

The column to add flag to.

index

Row numbers to add flag to.

flag

Flag to add to the data.frame.

Value

a data.frame with the same dimensions as data with the flags added to the appropriate column.

Examples

data <- add_flags(example_sondeproj$data, "fDOM_QSU", 2:7, "TEST01")
data$fDOM_QSU_flag[1:8]
