rbindDataframe: A fast method for concatenating data.frames
In genoset: A RangedSummarizedExperiment with methods for copy number analysis
Description

Details
Value
Description
Performs the same action as do.call(rbind, list_of_dataframes), but dramatically faster. Part
of the speed comes from assuming that all of the data.frames have the same column names and
types. If desirved an additional factor column can be added that specifies the original list
element associated with each row. The argument element.colname is used to name this column.
Usage
1
rbindDataframe(dflist, element.colname)
Arguments
dflist
list of data.frames
element.colname
scalar character, name for additional factor column giving the name
of the element of dflist corresponding to each row. dflist must be named to use this feature.
Details
For a list of 1000 data.frames with 884 rows and 12 columns rbindDataframe takes 0.553s and
do.call(rbind,x) takes 327.304s, a 600X speedup. This pure-R solution is made possible by
the lovely shallow copy features Michael Lawrence has added to base R.
