## Quality Assessment for MicroRNA Expression Estimates

### Description

This function produces several figures to examine quality scores.

### Usage

    qualityAssessment(object1, object2=NULL, cloglog1=FALSE, cloglog2=FALSE,
                      na.rm=FALSE, plotType=c("scatterplot","boxplot"),
                      label1=NULL, label2=NULL)

### Arguments

`object1` | a list containing two elements: ct (the expression estiamtes) and qc (quality scores)
`object2` | an optional second list of the same format as object1, used to compare two methods.
`cloglog1` | if TRUE, the -log(-log(object1$qc)) is plotted. This is useful to visualize certain quality scores such as R-squared.
`cloglog2` | if TRUE, the -log(-log(object2$qc)) is plotted. This is useful to visualize certain quality scores such as R-squared.
`na.rm` | if TRUE, quality scores corresponding to NA expression estimates are removed from analysis. This is only used if plotType=="boxplot".
`plotType` | type of plot to return. Options are a scatterplot or a boxplot.
`label1` | optional label corresponding to object 1 to be used in plotting.
`label2` | optional label corresponding to object 2 to be used in plotting.

### Value

The function generates a plot of the desired type.
