get_snp: Get SNPs from a data frame

In JulFriedrich/miRetrieve: miRNA Text Mining in Abstracts

Description

Get SNPs from a data frame.

Usage

get_snp(df, row = NULL, top = NULL, col.snp = SNPs, col.pmid = PMID)

Arguments

df	Data frame containing SNPs. If top is set, df must also contain PubMed IDs.
row	Integer. Optional. Specifies row from which SNP shall be obtained. Works best with a data frame listing counts only as from count_snp(). If neither row nor top is given, row is automatically set to 1.
top	Integer. Optional. Specifies number of most frequent SNPs to return.
col.snp	Symbol. Column containing SNPs.
col.pmid	Symbol. Column containing PubMed IDs. Necessary if the data frame provided is not a count data frame.

Details

Get SNPs from a data frame.

• If a data frame containing SNP counts as from count_snp() is provided, these SNPs are specified by the row they are listed in. To get the SNPs by row, set the row argument.

• If a data frame with PubMed IDs is provided, these SNPs are specified by their top occurrence. To get the SNPs by frequency, set the top argument.

If neither row nor top is provided, row is automatically set to 1.

Value

String or character vector containing SNPs.
