freqplot: A plotting function for SISPA sample identifiers

In SISPA: SISPA: Method for Sample Integrated Set Profile Analysis

Description

Given a sample changepoint data frame, will plot number of samples with and without profile activity

Usage

freqplot(x)

Arguments

x	A data frame containing samples as rows followed by zscores and estimated changepoints to be plotted.

Details

This function expects the output from cptSamples function of SISPA package, and shows the number of samples with (orange filled bars) and without profile activity (grey filled bars).

Value

Bar plot pdf illustrating distribution of samples

Examples

samples <- c("s1","s2","s3","s4","s5","s6","s7","s8","s9","s10")
zscores <- c(3.83,2.70,2.67,2.31,1.70,1.25,-0.42,-1.01,-2.43,-3.37)
changepoints <- c(1,1,1,2,2,3,3,NA,NA,NA)
sample_groups <- c(1,1,1,0,0,0,0,0,0,0)
my.data = data.frame(samples,zscores,changepoints,sample_groups)
freqplot(my.data)
