## Sort Genes According to the Value of a Statistic

### Description

Lists genes and corresponding statistics in decreasing order of the
statistics. This function applies to any type of statistic, including
log ratios, one and two-sample t-statistics, and F-statistics. Missing
values are ignored, as in `sort(..., na.last=NA)`

.

### Usage

stat.gnames(x, gnames, crit= 50)

### Arguments

`x` |
a numeric vector containing the statistics for each
gene. Missing values (NAs) are allowed. |

`gnames` |
a character vector containing the gene names. |

`crit` |
specifies the number of genes to be returned. If crit <
1, the crit*100% genes with the largest x values are listed. If crit
>= 1, the crit genes with the largest x values are listed. |

### Value

List containing the following components

`gnames` |
gene names sorted in decreasing order of the
statistics in x. |

`t` |
statistics sorted in decreasing order. |
