dbGetComparisons {maDB}R Documentation

Get a list of all comparisons from the database

Description

This function can be used to get all available information about comparisons that are stored in the database (i.e. which samples/signal channels are compared in which comparison).

Usage

dbGetComparisons(con, exp.title = NULL, join.tables = c("signal_channels", "samples", "arrays", "experiments"))

Arguments

con The connection to the database.
exp.title Get the comparisons that were created within a specific micro array experiment that was saved in the database. If not submitted all comparisons will be returned. To get the information about the experiments stored in the database, call dbGetExperimentInfo.
join.tables The tables with which the comparisons will be joined. In the default case (which means join to all tables) all information concerning the comparisons (which experiment, sample, array ... was used) will be returned.

Value

The function returns a table with rows corresponding to the comparisons and columns to the attributes of the different tables (column names ending in “red” belong to the red signal channel and column names ending in “green” to the green respectively).

Note

For further information and examples refer to the package vignette (which can be opened using openMadbVignette).
