FSRDistplot

FSRDistplot returns a ggplot object with the Forward Strand Ratio distribution plot to analyze strand imbalance in ChIP-exo data.

FSRDistplot(..., names.input = NULL, quantiles = c(0, 0.25, 0.5, 0.75, 1),
  depth.values = seq_len(30), both.strand = FALSE)

Arguments

...

a list of ExoData objects, or several ExoData objects by themselves.

names.input

a character vector with the names to use in the plot. If it is empty FSRDistplot is going to create the names as the names of the list when they are available or is going to name them as Sample: 1 ,... , Sample: k.

quantiles

a numeric vector with the quantiles used to estimate the FSR distribution at a given depth. The default value is c(0,.25,.5,.75,1))

depth.values

a numeric vector indicating the regions with depth less or equal to, that are going to be filtered out. The defaulta values are seq_len(50).

both.strand

a logical value indicating if the DataFrame contains only regions with reads aligned to both strand or all. The default value is FALSE.

Value

A ggplot2 object with the FSR distribution plot.
