## Visualisation functions

### Description

Functions to plot the subgraphs induced by the most significant GO terms

### Usage

    showSigOfNodes(GOdata, termsP.value, firstSigNodes = 10, reverse = TRUE,
                   sigForAll = TRUE, wantedNodes = NULL, putWN = TRUE,
                   putCL = 0, type = NULL, showEdges = TRUE,  swPlot = TRUE,
                   useFullNames = TRUE, oldSigNodes = NULL, useInfo = c("none", "pval", "counts", "def", "np", "all")[1],
                   plotFunction = GOplot, .NO.CHAR = 20)

    printGraph(object, result, firstSigNodes, refResult, ...)

### Arguments

`object` | an object of class `topGOdata`.
`GOdata` | an object of class `topGOdata`.
`result` | an object of class `topGOresult`.
`firstSigNodes` | the number of top scoring GO terms which ....
`refResult` | an object of class `topGOresult`.
`termsP.value` | named vector of p-values.
`reverse` | the direction of the edges.
`sigForAll` | if `TRUE` the score/p-value of all nodes in the DAG is shown, otherwise only the score for the `sigNodes`
`wantedNodes` | the nodes that we want to find, we will plot this nodes with a different color. The vector contains the names of the nodes
`putWN` | the graph is generated with using the firstSigNodes and the wantedNodes.
`putCL` | we generate the graph from the nodes given by all previous parameters, plus their children. if putCL = 1 than only the children are added, if putCL = n we get the nodes form the next n levels.
`type` | used for ploting pie charts
`showEdges` | if `TRUE` the edge are shown
`swPlot` | if true the graph is ploted, if not no ploting is done.
`useInfo` | aditional info to be ploted to each node.
`oldSigNodes` | used to plot the (new) sigNodes in the same collor range as the old ones
`useFullNames` | argument for internal use ..
`plotFunction` | argument for internal use ..
`.NO.CHAR` | argument for internal use ..
`...` | Extra arguments for `printGraph` can be: `fn.prefix` character string giving the file name prefix. `useInfo` as in `showSigOfNodes` function. `pdfSW` logical attribute switch between PDF or PS formats.

### Details

There are two functions available. The `showSigOfNodes` will plot the induced subgraph to the current graphic device. The `printGraph` is a warping function for `showSigOfNodes` and will save the resulting graph into a PDF or PS file.

In the plots, the significant nodes are represented as rectangles. The plotted graph is the upper induced graph generated by these significant nodes.

    data(GOdata)
    data(results.tGO)

    showSigOfNodes(GOdata, score(resultFisher), firstSigNodes = 5, useInfo = 'all')
    printGraph(GOdata, resultFisher, firstSigNodes = 5, fn.prefix = "sampleFile", useInfo = "all", pdfSW = TRUE)
