filter.rules {snpStats} | R Documentation

## Filter a set of imputation rules

### Description

Determine which imputation rules are broken by removal of some SNPs from a study. This function is needed because, when if it emerges that genotyping of some SNPs is not reliable, necessitating their removal from study, we would also wish to remove any SNPs imputed on the basis of these unreliable SNPs.

### Usage

    filter.rules(rules, snps.excluded, exclusions = TRUE)

### Arguments

`rules` | An object of class `"ImputationRules"` containing a set of imputation rules
`snps.excluded` | The names of the SNPs whose removal is to be investigated
`exclusions` | If `TRUE`, the names of the imputed SNPs which would be lost by removal of the SNPs listed in `snps.excluded`. If `FALSE`, the names of the imputed SNPs which would not be lost are returned

### Value

A character vector containing the names of imputed SNPs to be removed
