fetch.samples: Fetch samples from a phyloarray database

In microbiome/HITChipDB: HITChipDB

Description

The function fetches complete records from the samples table. If condition=NULL it will fetch all records and if condition is defined it will fetch only those records that comply with the condition. Condition must be a list of lists, each having at least the fields field and value. The field field must be a character vector of length 1 and value must be a vector. Each of the values will be evaluated as a optional value for the field field. This is an example: "list(list(field='projectName',value=c(A,B)))" that will be evaluated to the SQL condition "WHERE (projectName='A' OR projectName='B')".

Usage

fetch.samples(con, condition = NULL)

Arguments

con	MySQL connection
condition	list of lists with field-value pairs

Value

A dataframe with the selected records from the samples table
