plotZscore: Plots of z scores

Description

This is the main function to plot the z scores against cell ids.

Usage

plotZscore(
  data,
  cell_range = NULL,
  segment_size = 2,
  reference_lines = c(-1.65, 1.65)
)

Value

A grid of plots of z score against cell id of teh given features.

Arguments

data

Data frame. A data frame of cell id and features.

cell_range

Vector. A numeric vector of cell id range for which the plot should be displayed. Default is NULL, which plots all the cells.

segment_size

Integer. A numeric value to indicate the size of the bars in the plot. Default is 2.

reference_lines

Vector. A numeric vector of confidence interval values for the reference lines in the plot. Default is c(-1.65, 1.65).
