plotLitreApp: Plot interactive litre plots

In bigPint: Big multivariate data plotted interactively

Description

Plot interactive litre plots.

Usage

plotLitreApp(
  data = data,
  dataMetrics = dataMetrics,
  dataSE = NULL,
  geneList = NULL,
  pointColor = "orange",
  option = c("hexagon", "allPoints")
)

Arguments

data	DATA FRAME | Read counts
dataMetrics	LIST | Differential expression metrics
dataSE	SUMMARIZEDEXPERIMENT | Summarized experiment format that can be used in lieu of data; default NULL
geneList	CHARACTER ARRAY | List of gene IDs to be drawn onto the litre. Use this parameter if you have predetermined subset of genes to be drawn. Otherwise, all genes in the data object can be superimposed on the litre plot; default NULL
pointColor	CHARACTER STRING | Color of overlaid points on scatterplot matrix; default "orange"
option	CHARACTER STRING ["hexagon" | "allPoints"] | The background of plot; default "hexagon"; "allPoints" may be too slow depending on data

Value

A Shiny application that shows a litre plot background and allows users to superimpose the subset of genes determined to be superimposed through the dataMetrics or geneList parameter. The application allows users to order how to sequentially superimpose the genes by columns in the dataMetrics parameter.

Examples

# The first pair of examples use data and dataMetrics
# objects as input. The last pair of examples create the same plots now
# using the SummarizedExperiment (i.e. dataSE) object input.

# Example 1: Create an interactive litre plot for the logged data using
# default background of hexagons.

data(soybean_ir_sub)
data(soybean_ir_sub_metrics)
soybean_ir_sub_log <- soybean_ir_sub
soybean_ir_sub_log[,-1] <- log(soybean_ir_sub[,-1]+1)
app <- plotLitreApp(data = soybean_ir_sub_log,
    dataMetrics = soybean_ir_sub_metrics)
if (interactive()) {
    shiny::runApp(app, port = 1234, launch.browser = TRUE)
}

# Example 2: Repeat the same process, only now plot background data as 
# individual points. Note this may be too slow now that all points are drawn
# in the background.

app <- plotLitreApp(data = soybean_ir_sub_log,
    dataMetrics = soybean_ir_sub_metrics, option = "allPoints",
    pointColor = "red")
if (interactive()) {
    shiny::runApp(app)
}

# Below are the same pair of examples, only now using the
# SummarizedExperiment (i.e. dataSE) object as input.

# Example 1: Create an interactive litre plot for the logged data using
# default background of hexagons.

## Not run:

se_soybean_ir_sub_log <- se_soybean_ir_sub
assay(se_soybean_ir_sub_log) <-
   log(as.data.frame(assay(se_soybean_ir_sub_log))+1)
app <- plotLitreApp(dataSE = se_soybean_ir_sub_log)
if (interactive()) {
    shiny::runApp(app, port = 1234, launch.browser = TRUE)
}

## End(Not run)
