autoplot: Generic autoplot function

Description

autoplot is a generic function to visualize various data object, it tries to give better default graphics and customized choices for each data type, quick and convenient to explore your genomic data compare to low level ggplot method, it is much simpler and easy to produce fairly complicate graphics, though you may lose some flexibility for each layer.

Arguments

object

object to be plot.

columns

columns passed to method works for TxDb, EnsDb and OrganismDb.

label.color

when label turned on for gene model, this parameter controls label color.

arrow

arrow passed to geome_alignment function to control intron arrow attributes.

indel.col

indel colors.

ideogram

Weather to call plotIdeogram or not, default is FALSE, if TRUE, layout_karyogram will be called.

transpose

logical value, defaut TRUE, always make features from VCF as x, so we can use it to map to genomic position.

axis.text.angle

axis text angle.

axis.text.x

logical value indicates whether to show x axis and labels or not.

axis.text.y

logical value indicates whether to show y axis and labels or not.

hjust

horizontal just for axis text.

rownames.label

logical value indicates whether to show rownames of matrix as y label or not.

colnames.label

logical value indicates whether to show colnames of matrix as y label or not.

na.value

color for NA value.

rotate

pheno.plot

show pheno plot or not.

main_to_pheno

main matrix plot width to pheno plot width ratio.

padding

padding between plots.

assay.id

index for assay you are going to use.

geom

Geom to use (Single character for now). Please see section Geometry for details.

truncate.gaps

logical value indicate to truncate gaps or not.

truncate.fun

shrinkage function. Please see shrinkagefun in package biovizBase.

ratio

used in maxGap.

mode

Display mode for genomic features.

space.skip

space ratio between chromosome spaces in coordate genome.

coord

Coodinate system.

chr.weight

numeric vectors which sum to

legend

A logical value indicates whether to show legend or not. Default is TRUE

which

A GRanges object to subset the result, usually passed to the ScanBamParam function.

show.coverage

A logical value indicates whether to show coverage or not. This is used for geom "mismatch.summary".

resize.extra

A numeric value used to add buffer to intervals to compute stepping levels on.

bsgenome

A BSgenome object. Only need for geom "mismatch.summary".

xlab

x label.

ylab

y label.

label

logic value, default TRUE. To show label by the side of features.

facetByRow

A logical value, default is TRUE ,facet RleList by row. If FALSE, facet by column.

type

For Rle/RleList, "raw" plot everything, so be careful, that would be pretty slow if you have too much data. For "viewMins", "viewMaxs", "viewMeans", "viewSums", require extra arguments to slice the object. so users need to at least provide lower, more details and control please refer the the manual of slice function in IRanges. For "viewMins", "viewMaxs", we use viewWhichMin and viewWhichMax to get x scale, for "viewMeans", "viewSums", we use window midpoint as x.

For ExpreesionSet, ploting types.

layout

Layout including linear, circular and karyogram. for GenomicRangesList, it only supports circular layout.

method

method used for parsing coverage from bam files. 'estimate' use fast esitmated method and 'raw' use relatively slow parsing method.

test.method

test method

...

Extra parameters. Usually are those parameters used in autoplot to control aesthetics or geometries.

main

title.

stat

statistical transformation.

indName

When coerce GRangesList to GRanges, names created for each group.

coverage.col

coverage stroke color.

coverage.fill

coverage fill color.

group.selfish

Passed to addStepping, control whether to show each group as unique level or not. If set to FALSE, if two groups are not overlapped with each other, they will probably be layout in the same level to save space.

names.expr

names expression used for creating labels. For EnsDb objects either "tx_id", "gene_name" or "gene_id".

binwidth

width of the bins.

nbin

number of bins.

genome.axis

logical value, if TRUE, whenever possible, try to parse genomic postition for each column(e.g. RangedSummarizedExperiment), show column as exatcly the genomic position instead of showing them side by side and indexed from 1.

full.string

logical value. If TRUE, show full string of indels in plot for VCF.

ref.show

logical value. If TRUE, show REF in VCF at bottom track.

chr

characters indicates the seqnames to be subseted.

Value

• A ggplot object, so you can use common features from ggplot2 package to manipulate the plot.

Introduction

autoplot is redefined as generic s4 method inside this package, user could use autoplot in the way they are familiar with, and we are also setting limitation inside this package, like

• scales

{X scales is always genomic coordinates in most cases, x could be specified as start/end/midpoint when it's special geoms for interval data like point/line}

colors{ Try to use default color scheme defined in biovizBase package as possible as it can }

Faceting

Faceting in ggbio package is a little differnt from ggplot2 in several ways

{ The faceted column could only be seqnames or regions on the genome. So we limited the formula passing to facet argument, e.g something ~ seqnames, is accepted formula, you can change "something" to variable name in the elementMetadata. But you can not change the second part. } { Sometime, we need to view different regions, so we also have a facet_gr argument which accept a GRanges. If this is provided, it will override the default seqnames and use provided region to facet the graphics, this might be useful for different gene centric views. }
