This function requires the bigdata library section to be loaded.
bd.relational.intersection(x, y)
bdFrame or
data.frame.
bdFrame or
data.frame.
bdFrame or
data.frame containing
the intersection of each data sets' columns and a row for each
combination of rows in the input relations where the given
rows have the same value for the common columns of the input
relations, if any.
This function takes two inputs (
bdFrame or
data.frame
). The output contains the
intersection of each data sets' columns and a row for
each combination of rows in the input relations where
the given rows have the same value for the common columns
of the input relations, if any.
## Get a data.frame with column "a" and rows ## where column "a" is 8, 9, or 10. bd.relational.intersection(data.frame(a=1:10, b=11:20, c=21:30), data.frame(a=8:20))
