draw.profile: Draw a coverage profile

Description

This method draws a coverage profile for the coverage matrix that is passed as an argument to the method

Usage

"draw.profile"(data,outfile=NULL,...)
"draw.profile"(data,outfile=NULL,...)

Arguments

data

Matrix or list of matrices generated by the function cov.matrix

outfile

URL of the .png file where the plot will be created

...

Additional parameters

Details

Function to generate a plot in the .png format displaying the profile resulting from calculating the average of each row in the matrix generated by using the cov.matrix function. See the cov.matrix documentation for more details on the matrix used to draw the profile

Examples

  ## draw the coverage profile for a coverate matrix that was previously calculated 
  # using the cov.matrix function for a BAM file containing ChIP-seq data 
  # from a H3K36me3 histone modification experiment
  data(DF_H3K36me3)
  draw.profile(DF_H3K36me3,ylab="coverage",outfile="testProfile.png",main="testProfile",col="red")
  
  ## Now, draw two profiles for 2 different coverage matrices previously 
  # obtained for the same H3K36me3 histone modification experiment and its
  # respective 'control' file
  data(DF_H3K36me3_control)
  
  #create a list with the two matrices
  input_l=list(DF_H3K36me3,DF_H3K36me3_control)
  draw.profile(input_l,ylab="coverage",outfile="testProfile.png",main="testProfile")
