Plot FastQC data

qc_plot(qc, modules = "all")

# S3 method for qctable
print(x, ...)



An object of class qc_read or a path to the sample zipped fastqc result file.


Character vector containing the names of fastqc modules for which you want to import the data. Default is all. Allowed values include one or the combination of:

  • "Summary",

  • "Basic Statistics",

  • "Per base sequence quality",

  • "Per sequence quality scores",

  • "Per base sequence content",

  • "Per sequence GC content",

  • "Per base N content",

  • "Sequence Length Distribution",

  • "Sequence Duplication Levels",

  • "Overrepresented sequences",

  • "Adapter Content",

  • "Kmer Content"

Partial match of module names allowed. For example, you can use modules = "GC content", instead of the full names modules = "Per sequence GC content".


an object of class qctable.


other arguments.


Returns a list of ggplots containing the plot for specified modules..
