check_iData(iData, quietly = FALSE)
iData |
A data frame of indicator data. |
quietly |
Set |
The restrictions on iData are not extensive. It should be a data frame with only one required column
uCode which gives the code assigned to each unit (alphanumeric, not starting with a number). All other
columns are defined by corresponding entries in iMeta, with the following special exceptions:
Time is an optional column which allows panel data to be input, consisting of e.g. multiple rows for
each uCode: one for each Time value. This can be used to split a set of panel data into multiple coins
(a so-called "purse") which can be input to COINr functions. See new_coin() for more details.
uName is an optional column which specifies a longer name for each unit. If this column is not included,
unit codes (uCode) will be used as unit names where required.
Message if everything ok, else error messages.
