## Estimate And Plot Express And Non-express Features

### Description

For each cell line, any compared two replicates might have a portion of transcripts that express in one replicate but not the other, depending on what cutoff is used to define non-express. This function estimate and plot the proportion of disagreement using multiple cutoffs. Average is used when multiple two-replicate comparisons included.

### Usage

    plotNE(dat, steps = seq(-0.5, 12, 0.5), Ks = 0:3, pchK = seq_along(Ks) -
      1, plotcell = 1, ...)

### Arguments

`dat` | A `rnaseqcomp` S4 class object.
`steps` | A numeric vector specifying log-scale cutoffs to be used for calculation and plotting. (default: seq(-0.5, 12, 0.5))
`Ks` | A numeric vector specifying which cutoffs to be highlighted and to which the reported proportions to be corresponding.
`pchK` | Plot styles of highlight points corresponding to `Ks`. (default: seq_along(Ks) - 1)
`plotcell` | 1 or 2 indicating which cell line will be plotted. If values other than 1 and 2, both cell lines will be plotted. This value won't affect estimation for both cell lines. (default: 1)
`...` | Parameters for base function `plot`.

### Value

`plot` | NE plots of quantification pipelines for selected cell line by `plotcell`.
`NE` | A list of two matrices. The first matrix gives the proportion of disagreement and the second matrix gives the proportion of both replicates under (non-express) correspoinding cutoff `Ks`. Values are based on average of two cell lines.

### Examples

    data(simdata)
    condInfo <- factor(simdata$samp$condition)
    repInfo <- factor(simdata$samp$replicate)
    evaluationFeature <- rep(TRUE, nrow(simdata$meta))
    calibrationFeature <- simdata$meta$house & simdata$meta$chr == 'chr1'
    unitReference <- 1
    dat <- signalCalibrate(simdata$quant, condInfo, repInfo, evaluationFeature,
    calibrationFeature, unitReference, calibrationFeature2 = calibrationFeature)
    plotNE(dat)
