Allows you to get the "ERR" indicator in dynamics by day, week, month.

## Usage

tg_channel_err(
channel_id = tg_get_channel_id(),
start_date = Sys.Date() - 15,
end_date = Sys.Date(),
group = c("day", "week", "month")
)

## Arguments

channel_id

start_date

Start date of report period

end_date

End date of report period

group

Time group: day, week, month

## Value

tibble with channel ERR dinamics

## Details

For the group = 'day' grouping, the value for the "average coverage of publications" as of the end of the day will be returned. For groupings group = 'week' and group = 'month', the value of the indicator "average coverage of publications" at the end of the last day of the period (week or month) will be returned. By default, the result will be returned for the last 10 days. However, you can specify the required period using the start_date and end_date parameters, while observing the restrictions on your tariff. Depending on the requested grouping type group - the period field will take one of the following formats:

• day: Y-m-d

• week: Y-W

• month: Y-m

## Examples

if (FALSE) {
tg_set_channel_id('R4marketing')
err <- tg_channel_err()
}
