Calculate a score range for multiple signals

calcSignalRange(
    data,
    chrom = NULL,
    chromstart = 1,
    chromend = .Machine$integer.max,
    assembly = "hg38",
    negData = FALSE)

Arguments

data: List of data to be plotted as character values specifying multiple bigwig file paths, dataframes in BED format, or GRanges objects with metadata column score.
chrom: Chromosome of data region ragne as a string, if range for a specific chromosome is desired.
chromstart: Integer start position on chromosome to get data range.
chromend: Integer end position on chromosome to get data range.
assembly: Default genome assembly as a string or a assembly object. Default value is assembly = "hg38".
negData: A logical value indicating whether any of the data has both positive and negative scores and the signal range should be adjusted accordingly. Default value is negData = FALSE.

Value

Returns a vector of length 2 with the calculated c(min, max) range.
