w_analysis: Shows the number of dense zones obtained with different...
In TFHAZ: Transcription Factor High Accumulation Zones

Description Usage Arguments Value Examples

This function is used to plot the number of dense zones and the total number of bases belonging to these dense zones present in a set of inputs, obtained (all with accumulation threshold=1) using the dense_zones function, for the same accumulation type, same chromosome, and different values of w half-width of the window defining the neighborhood of each base. The plot (with x axis logarithmic-scale) is generated only if all input data refer to the same accumulation type, otherwise an error message appears. Beside helping in comparing results obtained with different values of w, this function supports finding the best value of w to be used in further analysis.

1	w_analysis(input_list, chr = NULL)

`input_list`	a list containing multiple outputs of the dense_zones function, obtained for the same accumulation type, same chromosome and different values of w.
`chr`	optional argument, needed if the input was found with chr = "all"; a string or a vector containing strings with the name of the chromosome(s) (e.g., "chr1" or c("chr1", "chr4")) to be considered

None, the function is invoked for its side effect.
