TCGAvisualize_meanMethylation {TCGAbiolinks} | R Documentation

## Mean methylation boxplot

### Description

Creates a mean methylation boxplot for groups (groupCol), subgroups will be highlited as shapes if the subgroupCol was set.

Observation: Data is a summarizedExperiment.

### Usage

    TCGAvisualize_meanMethylation(data, groupCol = NULL,
      subgroupCol = NULL, shapes = NULL, print.pvalue = FALSE,
      plot.jitter = TRUE, jitter.size = 3, filename = "groupMeanMet.pdf",
      ylab = expression(paste("Mean DNA methylation (", beta, "-values)")),
      xlab = NULL, title = "Mean DNA methylation", labels = NULL,
      group.legend = NULL, subgroup.legend = NULL, color = NULL,
      y.limits = NULL, sort, order, legend.position = "top",
      legend.title.position = "top", legend.ncols = 3,
      add.axis.x.text = TRUE, width = 10, height = 10, dpi = 600,
      axis.text.x.angle = 90)

### Arguments

`data` | SummarizedExperiment object obtained from TCGAPrepare
`groupCol` | Columns in colData(data) that defines the groups. If no columns defined a columns called "Patients" will be used
`subgroupCol` | Columns in colData(data) that defines the subgroups.
`shapes` | Shape vector of the subgroups. It must have the size of the levels of the subgroups. Example: shapes = c(21,23) if for two levels
`print.pvalue` | Print p-value for two groups
`plot.jitter` | Plot jitter? Default TRUE
`jitter.size` | Plot jitter size? Default 3
`filename` | The name of the pdf that will be saved
`ylab` | y axis text in the plot
`xlab` | x axis text in the plot
`title` | main title in the plot
`labels` | Labels of the groups
`group.legend` | Name of the group legend. DEFAULT: groupCol
`subgroup.legend` | Name of the subgroup legend. DEFAULT: subgroupCol
`color` | vector of colors to be used in graph
`y.limits` | Change lower/upper y-axis limit
`sort` | Sort boxplot by mean or median. Possible values: mean.asc, mean.desc, median.asc, meadian.desc
`order` | Order of the boxplots
`legend.position` | Legend position ("top", "right","left","bottom")
`legend.title.position` | Legend title position ("top", "right","left","bottom")
`legend.ncols` | Number of columns of the legend
`add.axis.x.text` | Add text to x-axis? Default: FALSE
`width` | Plot width default:10
`height` | Plot height default:10
`dpi` | Pdf dpi default:600
`axis.text.x.angle` | Angle of text in the x axis
