simplifyResult {InterMineR} | R Documentation

## Convert multiple values of a column into Comma-separated character strings

### Description

This function converts the values of a column variable within a dataset into comma-separated, character strings. The process is achieved by using another column of the same dataset as index.

### Usage

    simplifyResult(
      dataset,
      index_column,
      values_column,
      returnInDataframe = FALSE
    )

### Arguments

`dataset` | a data.frame containing the data
`index_column` | a character string or a numeric/integer value indicating the column which will be used as index.
`values_column` | a character string or a numeric/integer value indicating the column whose values will be converted into comma-separated, character strings.
`returnInDataframe` | a logical value indicating whether to return only the converted columns or to append the character strings to the dataset.

### Value

If returnInDataframe argument is set to FALSE then a data.frame is returned with the unique values of the index column and the character strings of the values_column that correspond to each.

If returnInDataframe argument is set to TRUE then the original dataset is returned containing an extra column in which the character strings of the values_column have been appended.

### Examples

    # get HumanMine
    im.human = initInterMine(listMines()["HumanMine"])

    # get template query for retrieving GOTerms for specific genes
    qGene_GO = getTemplateQuery(im.human, "Gene_GO")

    # retrieve GOTerms for four different genes
    rGene_GO = list(NULL)
    for(i in seq(length(c("PPARG", "RPL5", "RPL11", "TP53")))){

      g = c("PPARG", "RPL5", "RPL11", "TP53")[i]
      qGene_GO$where[[1]]$value = g
      rGene_GO[[i]] = runQuery(im.human, qGene_GO)

    }

    # rbind results to data.frame
    rGene_GO = do.call(rbind, rGene_GO)

    # return simplified GOTerms results for each Gene
    simplify_GOTerms = simplifyResult(
      dataset = rGene_GO,
      index_column = "Gene.symbol",
      values_column = "Gene.goAnnotation.ontologyTerm.identifier",
      returnInDataframe = FALSE
    )

    # return simplified GOTerms results for each Gene, within the original data.frame
    simplify_GOTerms.2 = simplifyResult(
      dataset = rGene_GO,
      index_column = "Gene.symbol",
      values_column = "Gene.goAnnotation.ontologyTerm.identifier",
      returnInDataframe = TRUE
    )
