plotMetaDataExpl {TarSeqQC} | R Documentation

## Graphical exploration of a specific metadata column.

### Description

`plotMetaDataExpl` plots density and box-plot of a specific metadata column. If the characteristic is nonnumerical, then a frequency plot is built.

### Usage

    plotMetaDataExpl(object, name = c("length", "gc", "pool"), log = FALSE,
        join = TRUE, absolute = FALSE, color = "blue")

    ## S4 method for signature 'TargetExperiment'
    plotMetaDataExpl(object, name = c("length", "gc",
        "pool"), log = FALSE, join = TRUE, absolute = FALSE, color = "blue")

### Arguments

`object` | TargetExperiment class object.
`name` | a character indicating the metadata column name that should be analyzed.
`log` | Logical indicating if the numerical metadata column should be considered in log10 scale.
`join` | Logical only for numerical variables. It indicates if boxplot and density function should be plotted together using the ggplot2 geom_violin method.
`absolute` | Logical indicating if the frequencies of the selected categorical metadata column should be in absolute scale. If absolute is FALSE the frequencies are in relative percentages.
`color` | A character indicating a valid name color.

### Value

ggplot2 graphics.

### Note

see full example in `TargetExperiment-class`

### Examples

    ## Loading the TargetExperiment object
    data(ampliPanel, package="TarSeqQC")

    # Attribute boxplot and density plot exploration
    g<-plotMetaDataExpl(ampliPanel, name="length")
    if(interactive())
    {
    # x11(type="cairo")
    g
    }
    # Explore amount of amplicons per gene
    g<-plotMetaDataExpl(ampliPanel, name="gene", absolute=TRUE)
    if(interactive())
    {
    # x11(type="cairo")
    g
    }
