Description Usage Arguments Value Author(s) See Also Examples

Extract subset of columns from a data frame or a list of data frames by intersecting on a particular row. This function outputs a data frame which set of columns is a product of intersecting on a particular row of the imput data frame(s) columns with a given set of names (subset).

## Static method (use this):
## Subset$byRow(frameData, subset, row, verbose=FALSE, ...)

## Don't use the below:
## S3 method for class 'Subset'
byRow(static, frameData, subset, row, verbose=FALSE, ...)

`frameData`	Input `data.frame` or a `list` of data frames.
`subset`	`character` `vector` of names partially intersecting with given `data.frame` row and defining the set on which merging is to be performed.
`row`	The row on which the intersection is to be performed.
`verbose`	If `TRUE` enables diagnostic messages. Default is `FALSE`.
`...`	Not used

A data.frame or list of data frames which column set is a product of intersecting of a particular row with a (partially intersecting) subset.
