plot most variable k peaks (default k = 100) among all samples
     
    
    Usage
    heatmap_var_peaks(results, heatmap.peak.count = 100, ...)
 
    
    Arguments
    - results
- cinaR result object 
- heatmap.peak.count
- number of peaks to be plotted.
If number of peaks are less than k then all peaks will be used. 
- ...
- additional arguments for heatmap function, for more info `?pheatmap` 
 
    
    
    Examples
    library(cinaR)
data(atac_seq_consensus_bm) # calls 'bed'
# creating dummy results
results <- NULL
results[["cp"]] <- bed[,c(4:25)]
heatmap_var_peaks(results)
