MatchedGRanges-class | R Documentation |
The MatchedGRanges
class is a subclass of both
Matched
and GRanges
. Therefore, it contains slots
and methods for both of these classes.
The MatchedGRanges
class uses a delegate object
during initialization to assign its GRanges
slots.
MatchedGRanges
behaves as a GRanges
but also
includes additional Matched
object functionality
(see ?Matched
). For more information about
GRanges
see ?GenomicRanges::GRanges
.
focal
A GRanges
object containing the focal
data to match.
pool
A GRanges
object containing the pool
from which to select matches.
delegate
A GRanges
object used to initialize
GRanges
-specific slots. matchRanges()
assigns
the matched set to the slot.
matchedData
A data.table
with matched data
matchedIndex
An integer vector corresponding
to the indices in the pool
which comprise the
matched
set.
covar
A character vector describing the covariates used for matching.
method
Character describing replacement method used for matching.
replace
TRUE/FALSE describing if matching was done with or without replacement.
seqnames
seqnames(delegate)
ranges
ranges(delegate)
strand
strand(delegate)
seqinfo
seqinfo(delegate)
elementMetadata
elementMetadata(delegate)
elementType
elementType(delegate)
metadata
metadata(delegate)
Functions that get data from Matched subclasses (x
)
such as MatchedDataFrame, MatchedGRanges,
and MatchedGInteractions are listed below:
matchedData(x)
: Get matched data from a Matched object
covariates(x)
: Get covariates from a Matched object
method(x)
: Get matching method used for Matched object
withReplacement(x)
: Get replace method
indices(x, set)
: Get indices of matched set
For more detail check the help pages for these functions.
Additional functions that get data from Matched subclasses
(x
) such as MatchedDataFrame, MatchedGRanges,
and MatchedGInteractions include:
focal(x)
: Get focal set from a Matched object
pool(x)
: Get pool set from a Matched object
matched(x)
: Get matched set from a Matched object
unmatched(x)
: Get unmatched set from a Matched object
For more detail check the help pages for these functions.

## Contructing MatchedGRanges with matchRanges
set.seed(123)
gr <- makeExampleMatchedDataSet(type = "GRanges")
mgr <- matchRanges(
focal = gr[gr$feature1, ],
pool = gr[!gr$feature1, ],
covar = ~ feature2 + feature3,
method = "rejection",
replace = FALSE
)
class(mgr)
## Make MatchedGRanges example
set.seed(123)
x <- makeExampleMatchedDataSet(type = "GRanges", matched = TRUE)
## Accessor functions for Matched class
