xgobi.FCS {rflowcyt} | R Documentation |
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.
xgobi.FCS(myFCSobj, subset.row = NULL, subset.col = NULL, ...)
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 |

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