xgobi.FCS {rflowcyt} | R Documentation

## XGobi: Dynamic Graphics for Data Analysis on FCS R objects

### Description

This function allows for a multidimensional view/manipulation of the data of the FCS object. Each row is an observation/cell, and the columns are regarded as the different variable conditions.

### Usage

      xgobi.FCS(myFCSobj, subset.row = NULL, subset.col = NULL, ...)

### Arguments

`myFCSobj` | FCS object
`subset.row` | a vector of the row positions to be displayed; by default the first 1/15th rows are chosen to be displayed
`subset.col` | a vector of the column positions to be displayed; by default the first 1/2 of the columns are displayed
`...` | additional 'xgobi' function parameters/options in 'xgobi' package

### Value

A graphics window with user-enabled manipulations The UNIX `status' upon completion, i.e. `0' if ok.

### WARNING

Abuses/uses xgobi: XGobi cannot handle datasets that are too large. Therefore, use subset.col and subset.row options to reduce the data matrix of the FCS R-object. Please see `xgobi' for other commands in the signature.

### Note

By default only a subset of the data is shown in xgobi because of size limitations. The user may be able to view the whole FCS dataset by using xgobi, but only if the dataset is not too huge for xgobi capabilities. It may be advisable to `createGate` and `extractGatedData` before viewing with xgobi.

### Examples

      if (require(xgobi)) {
       if (require(rfcdmin)){
        ## obtaining the FCS objects from VRC data
        if (!(is.element("unst.1829", objects()))) {
          data(VRCmin)
        }
        if (interactive()==TRUE) {
          ## plots first 1/15 rows
          ## plots first 1/2 columns
          xgobi.FCS(unst.1829, title="unst.1829 default subset")

          ## plots all the rows
          ## plots only the first 3 columns
          xgobi.FCS(unst.1829, subset.row=1:6000, subset.col=1:2,
                    title="unst.1829 first 6000 rows/cells with 2 column params")
        }
      }
     }
