deviation.plot.beta
Description
Creates a deviation plot based on the methylation beta values of a population.
Usage
deviation.plot.beta(betas, c.values = NULL, c.legend = NULL)
Arguments
betas |
Non-empty numeric matrix of methylation beta values. Rows in this matrix must denote sites or
regions, and columns - samples. If a locus (row in the matrix) contains missing values only, it is
not included in the plot.
|
c.values |
Vector (usually a factor ) storing category or quantitative values for each site or region. The
length of this vector must be equal to nrow(betas) , the i-th element storing the
property values for the i-th locus in betas . Note that this vector's names, if present,
are ignored.
|
c.legend |
If c.values stores categories, this parameter specifies the mapping from property values to
colors. The mapping is in the form of a named character vector. All values that appear in
c.values must be present among the names of this vector. The order of the values in this
mapping determines in which order the colors are stacked (when the number of loci is large). If
c.values denotes a quantitative measure, this parameter is a singleton integer ,
specifying the color scheme for visualizing the values. Currently, the only supported values are
2 and 3 . See rnb.options for more details.

Value
Methylation variability as a number between 0
and 1
, invisibly. This number denotes the relative
area of variation in the generated plot.
