ReplaceColumn(TColumnKey, ISeriesTRowKey) |
Mutates the data frame by replacing the specified series with
a new series. (If the series does not exist, only the new
series is added.)
## Parameters
- `column` - A key (or name) for the column to be replaced or added
- `series` - A data series to be used (the row key type has to match)

ReplaceColumnV(TColumnKey, IEnumerableV) |
Mutates the data frame by replacing the specified series with
a new data sequence . (If the series does not exist, only the new
series is added.)
## Parameters
- `column` - A key (or name) for the column to be replaced or added
- `series` - A sequence of values to be added

ReplaceColumn(TColumnKey, ISeriesTRowKey, Lookup) |
Mutates the data frame by replacing the specified series with
a new series. (If the series does not exist, only the new series is added.)
When adding a series, the specified `lookup` parameter is used for matching
keys. The parameter can only be used for frame with ordered indices.
## Parameters
- `column` - A key (or name) for the column to be replaced or added
- `series` - A data series to be used (the row key type has to match)
- `lookup` - Specify how to find value in the added series (look for
nearest available value with the smaller/greater key).

ReplaceColumnV(TColumnKey, IEnumerableV, Lookup) |
Mutates the data frame by replacing the specified series with
a new data sequence. (If the series does not exist, only the new series is added.)
When adding a series, the specified `lookup` parameter is used for filling
missing values (e.g. `null` or `NaN`). The parameter can only be used for
frame with ordered indices.
## Parameters
- `column` - A key (or name) for the column to be replaced or added
- `series` - A data series to be used (the row key type has to match)
- `lookup` - Specify how to find value in the added series (look for
nearest available value with the smaller/greater key).
