Load data, choose a style, and choose output method

Description

This function loads a flowFrame of flowSet and invokes the plotting function. Choose a theme: 'viridis', 'bigfoot', or 'aurora'. Viridis is colourblind accessible. Choose to save to the working directory or display in current session. Choose the number of bins (granularity) of the data. You can normalize to the max median signal for "clean" files. If you misspell an option it will give an error.

Usage

spectralplot(
  flowfile,
  theme = "viridis",
  save = FALSE,
  bins = 512,
  normalize = FALSE,
  params = NULL,
  guessPop = FALSE,
  unstained = NULL
)

Arguments

flowfile

A flowSet or flowFrame.

theme

Choose a theme: 'viridis' (default), 'bigfoot', or 'aurora'.

save

FALSE: in console (default). TRUE : as png file in working directory.

bins

Choose the granularity of the data. Between 200 and 1000 works well for most data.

normalize

Normalize the data to the max median signal (only for clean signals). TRUE or FALSE (default).

params

Specify parameters (in order) to plot. If NULL (default), parameters will be selected based on the cytometer model.

guessPop

Try to select only the positive spectral signal (200 events). It is recommend to set normalize to TRUE when using guessPop.

unstained

flowFrame of the negative data, only needed if guessPop = TRUE

Value

Images of full spectrum

Examples


## flowSpectrum has one demo file that can be loaded.  
ff <- read.FCS(system.file("extdata", "PE.fcs", package = "flowSpectrum"))

## create plots using spectralplot().
spectralplot(ff, theme='viridis', save=FALSE, bins=512, normalize=FALSE, params=NULL)

## load flowSet and run spectralPlot()
fs <- read.flowSet(list.files('C:/Users/Chris/testspectra', full.names = TRUE))
spectralPlot(fs)

## If the parameters are out of order, or you want a custom order, you need to create a character vector
params <- grep("-W|-H|Time|SC",ff@parameters@data$name,value = TRUE, invert=TRUE)

## If the spectra is "unclean"
spectralPlot(fs, guessPop = TRUE, normalize = TRUE)
