plotECDF.FCS {rflowcyt} | R Documentation

## Create a empirical cumulative distribution plot for one (or more) parameter(s) of one (or more) FCS object(s)

### Description

Create a empirical cumulative distribution plot for one parameter of one (or more) FCS object(s).

### Usage

    plotECDF.FCS(data, varpos, var.list, group.list, xlab,
    ylab,alternating=TRUE, legend.title=NULL,...)

### Arguments

`data` | a list of fluorescent data from one (or more) FCS object(s)
`varpos` | the numerical column variable position of the data of the FCS object
`var.list` | conditioning variables
`group.list` | a variable or expression to be evaluated in the data frame specified by 'data', expected to act as a grouping variable within each panel, typically used to distinguish different groups by varying graphical parameters like color and line type
`xlab` | a title for the x axis
`ylab` | a title for the y axis
`alternating` | logical specifying whether axis labels should alternate from one side of the group of panels to the other (for more details see `xyplot`)
`legend.title` | a title for the legend
`...` | any other arguments are passed to the `xyplot` function

### Details

Other options from the functions `xyplot` from the `lattice` library.

### Value

None.

### Examples

     require(lattice)

     ##Example I:
     data(flowcyt.data)

     ##Draw an empirical cumulative density plot for the Foward scatter
     ##parameter of the different stains at a particular different time point
     ##(one panel per time point).
     plotECDF.FCS(flowcyt.data,varpos=c(1),var.list=c(paste("time",1:12,sep="")),group.list=paste("Stain",c(1:8),sep=""),main="ECDF plot of the FSC parameter for different stains across time points",lwd=2,cex=1.5,type="l")

     ##Example II:
     if (require(rfcdmin)) {
      ##Obtain the location of the fcs files
      pathFiles<-system.file("bccrc", package="rfcdmin")
      drugFiles<-dir(pathFiles)

      ##Read a serie of FCS files
      drugData<-read.series.FCS(drugFiles,path=pathFiles,MY.DEBUG=FALSE)
      }

      ##Draw a empirical cumulative density plot for the Foward scatter
     ##parameter for the differents aliquots (of the same cell line)
     ##treated with different compounds.
     plotECDF.FCS(drugData,varpos=c(1),var.list=c("Serie"),group.list=paste("compound",c(1:8),sep=""),main="ECDF plot for the aliquots treated with different compounds.",lwd=2,cex=1.5,type="l")
