## Flow cytometry data from five samples from a patient

### Description

Flow cytometry data from blood samples taken from a Leukemia patient before and after allogenic bone marrow transplant. The data spans five visits.

### Usage

    data(gvhd10)

### Format

A data frame with 113896 observations on the following 8 variables.

`FSC.H`

  forward scatter height values

`SSC.H`

  side scatter height values

`FL1.H`

  intensity (height) in the FL1 channel

`FL2.H`

  intensity (height) in the FL2 channel

`FL3.H`

  intensity (height) in the FL3 channel

`FL2.A`

  intensity (area) in the FL2 channel

`FL4.H`

  intensity (height) in the FL4 channel

`Days`

  a factor with levels `-6` `0` `6` `13` `20` `27` `34`
