att {RedeR} | R Documentation

## Map and set edge and vertex attributes to RedeR application.

### Description

These functions map data frames containing edge/vertex attributes to an igraph object and set attributes to RedeR.

### Usage

    att.setv(g, from, to='nodeColor', pal=1, cols=NULL, na.col=grey(0.7), xlim=c(20,100,1), shapes=NULL, breaks=NULL, categvec=NULL, nquant=NULL, isrev=FALSE, getleg=TRUE, roundleg=1, title=NULL)
    att.sete(g, from, to='edgeColor', pal=1, cols=NULL, na.col=grey(0.7), xlim=c(20,100,1), shapes=NULL, breaks=NULL, categvec=NULL, nquant=NULL, isrev=FALSE, getleg=TRUE, roundleg=1, title=NULL)
    att.mapv(g, dat, refcol=1)
    att.mape(g, dat, refcol=c(1,2))

### Arguments

`g` | An igraph object.
`from` | An attribute name available in 'g' <string>.
`to` | A valid RedeR attribute name (see `addGraph` or type 'att.setv()' or 'att.sete()').
`breaks` | A numeric vector of two or more breakpoints to be applied to the attribute values.
`pal` | Default color palette. Options: 1 or 2.
`xlim` | A numeric vector with three boundaries: c(<lower boundary>, <upper boundary>, <NA>). It corresponds to boundary values to be apply to numeric attributes (e.g. nodeSize). Default: c(20,100,1).
`cols` | Vector of colors (either hexadecimals or valid R color names).
`na.col` | A color representing eventual NAs. Default: grey(0.7)
`shapes` | A string vector with valid RedeR shapes (see `addGraph` or type 'att.setv()' or 'att.sete()').
`categvec` | Optional: levels to encode attributes as a factor <vector>.
`nquant` | Optional: number of breakpoints to split attribute values by quantiles <integer>.
`isrev` | Optional: reversed version of attribute values <logical>.
`getleg` | Optional: return legend values <logical>.
`dat` | A data frame with the attributes to be mapped to 'g'.
`refcol` | The reference columns in the 'data' object with either node ids (one column <integer>) or edge ids (two columns <vector of two integers>).
`roundleg` | Integer indicating the number of decimal places (round) in the legend of numerical attributes

.

`title` | Optional: legend title

.

### Examples

    data(ER.deg)

    sg <- ER.deg$ceg  # an igraph object
    dt <- ER.deg$dat  # a data frame object

    # maps the data frame to the igraph object
    sg <- att.mapv(g=sg, dat=dt, refcol=1)

    # Sets graph attributes to RedeR!

    # sets gene symbol do nodeAlias attribute
    sg <- att.setv(sg, from="Symbol", to="nodeAlias")

    # sets numerical value to nodeColor attribute
    sg <- att.setv(sg, from="logFC.t3", to="nodeColor", breaks=seq(-1,1,0.2), pal=2)

    # sets numerical value to nodeSize attribute
    sg <- att.setv(sg, from="ERbdist", to="nodeSize", nquant=10, isrev=TRUE, xlim=c(5,40,1))
