append2List: append2List

In kzouchka/Director: A dynamic visualization tool of multi-level data

Description

Appends a data frame containing additional relationship information to an existing List having 6 columns: source, target, description, value, sourcefc, targetfc. Order matters! For example, add a map of transcripts to genes to a List of miRNAs and their target transcripts so that the final List connects miRNAs -> transcripts -> genes.

Usage

append2List(List, appendList, description = "description",
  sourcefc = "sourcefc", targetfc = "targetfc", value = "value",
  target = "target", source = "source", appendMatch = TRUE)

Arguments

List	Data frame containing the necessary columns above. e.g. Formatted with createList function.
appendList	Data frame or matrix to append to List.
description	Column name of appendList corresponding to the descriptions to append.
sourcefc	Column name of appendList corresponding to the sourcefcs to append.
targetfc	Column name of appendList correspondig to the targetfcs to append.
value	Column name of appendList correspondig to the relationship values to append.
target	Column name of appendList corresponding to the targets to append.
source	Column name of appendList corresponding to the sources to append.
appendMatch	Filter and remove 1) rows in List that contain targets without a corresponding source in appendList, and 2) rows in appendList that contain sources without a corresponding target in List.

Value

a combined List.

Examples

tempList <- createList(data.frame(source=c("A","B","C"),
    target=c("D","E","G"),
    description=c("consonant","vowel","consonant"),
    value=runif(3,-1,1),
    sourcefc=runif(3,-2,2),
    targetfc=runif(3,-2,2)))
tempAppendList <- data.frame(source="D",target="I",
    description="vowel",value=runif(1,-1,1),
    sourcefc=runif(1,-2,2), targetfc=runif(1,-2,2))
append2List(tempList,tempAppendList) # Will combine only 1 row from each list.
append2List(tempList,tempAppendList, appendMatch=FALSE) # Will combine all rows
