collection_period: Get the earliest and latest of your data
In lucidviews/repvisForODK: Analyse data from ODK Central

Description Usage Arguments Value Examples

The function finds the earliest and the latest submission dates in a data frame. It accounts for different spellings of the submission date column by applying a case-insensitive RegEx formula that matches every combination of the words 'submission' and 'date'. Please note, that one and only one of the three data arguments (df, csv, svc) must be specified.

1	collection_period(df = NULL, csv = NULL, svc = FALSE, date_col)

`df`	Data frame containing the ODK data that is to be used. Optional, defaults to NULL.
`csv`	Character that specifies the path to the csv file that is to be read. Optional, defaults to NULL.
`svc`	Logical that indicates whether the data shall be parsed using ruODK's `odata_submission_get`. Optional, defaults to FALSE.
`date_col`	String that specifies the date or time stamp column in the data which is to be examined.
