cdsw {specL}R Documentation

Generate Dynamic SWATH Window

Description

This function computes dynamic SWATH windows (cdsw) for a given vector of numeric values, an psmSet class, or an specLSet class. The input R data object can be generated using the read.bibliospec function.

Usage

    cdsw(x, n=20, overlap=1, ...)

Arguments

x

Numeric vector or psmSet class.

n

Number of desired SWATH windows. Default is set to 20.

overlap

Overlap of SWATH windows. The default is 1 Dalton.

...

pass arguments to hist function.

Details

The function determines the SWATH windows using the quantile function.

Value

The output is data.frame having the attributes from, to, mid, width, and counts. In the ideal output all bins should contain the same number of numeric values. This requirement is violated because the window borders are rounded with no digit after the comma.

Examples


  # do not plot histogram
  cdsw(peptideStd, plot = FALSE,  overlap = 0)
  
  # plot hist
  cdsw(peptideStd, freq = TRUE)
  
  # pre-filtering
  ## cdsw(x=q1[350 <= q1 & q1 <= 1250], n=20, overlap = 0, freq=TRUE)
