# Quality Assessment for MicroRNA Expression Estimates

### Description

This function produces several figures to examine quality scores.

### Usage

1 2 3 |

### 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.
