trelli_abundance_heatmap: Heatmap trelliscope building function for abundance data

In pmartR/pmartRqc: Panomics Marketplace - Quality Control and Statistical Analysis for Panomics Data

Heatmap trelliscope building function for abundance data

Description

Specify a plot design and cognostics for the abundance heatmap trelliscope. Data must be grouped by an e_meta column. Main_effects order the y-variables. All statRes data is ignored. For RNA-Seq data, use "trelli_rnaseq_heatmap".

Usage

trelli_abundance_heatmap(
  trelliData,
  cognostics = c("sample count", "mean abundance", "biomolecule count"),
  ggplot_params = NULL,
  interactive = FALSE,
  path = .getDownloadsFolder(),
  name = "Trelliscope",
  test_mode = FALSE,
  test_example = 1,
  single_plot = FALSE,
  ...
)

Arguments

trelliData	A trelliscope data object made by as.trelliData, and grouped by an emeta variable. Required.
cognostics	A vector of cognostic options. Defaults are "sample count", "mean abundance" and "biomolecule count". "sample count" and "mean abundance" are reported per group, and "biomolecule count" is the total number of biomolecules in the biomolecule class (e_meta column).
ggplot_params	An optional vector of strings of ggplot parameters to the backend ggplot function. For example, c("ylab(”)", "xlab(”)"). Default is NULL.
interactive	A logical argument indicating whether the plots should be interactive or not. Interactive plots are ggplots piped to ggplotly (for now). Default is FALSE.
path	The base directory of the trelliscope application. Default is Downloads.
name	The name of the display. Default is Trelliscope
test_mode	A logical to return a smaller trelliscope to confirm plot and design. Default is FALSE.
test_example	A vector of plot indices to return for test_mode. Default is 1.
single_plot	A TRUE/FALSE to indicate whether 1 plot (not a trelliscope) should be returned. Default is FALSE.
...	Additional arguments to be passed on to the trelli builder

Value

No return value, builds a trelliscope display of heatmaps that is stored in 'path'

Examples

if (interactive()) {
library(pmartRdata)

# Transform the data
omicsData <- edata_transform(omicsData = pep_object, data_scale = "log2")

# Group the data by condition
omicsData <- group_designation(omicsData = omicsData, main_effects = c("Phenotype"))

# Apply the IMD ANOVA filter
imdanova_Filt <- imdanova_filter(omicsData = omicsData)
omicsData <- applyFilt(filter_object = imdanova_Filt, omicsData = omicsData,
                       min_nonmiss_anova = 2)

# Normalize my pepData
omicsData <- normalize_global(omicsData, "subset_fn" = "all", "norm_fn" = "median",
                             "apply_norm" = TRUE, "backtransform" = TRUE)

# Implement the IMD ANOVA method and compute all pairwise comparisons 
# (i.e. leave the `comparisons` argument NULL)
statRes <- imd_anova(omicsData = omicsData, test_method = 'combined')

# Generate the trelliData object
trelliData2 <- as.trelliData(omicsData = omicsData)
trelliData4 <- as.trelliData(omicsData = omicsData, statRes = statRes)

# Build the abundance heatmap with an omicsData object with emeta variables. 
# Generate trelliData in as.trelliData.
trelli_panel_by(trelliData = trelliData2, panel = "RazorProtein") %>%
   trelli_abundance_heatmap(test_mode = TRUE, test_example = 1:3, path = tempdir())
   
# Users can modify the plotting function with ggplot parameters and interactivity, 
# and can also select certain cognostics.     
trelli_panel_by(trelliData = trelliData4, panel = "RazorProtein") %>% 
   trelli_abundance_heatmap(
     test_mode = TRUE, test_example = 1:5, 
     ggplot_params = c("ylab('')", "xlab('')"), 
     interactive = TRUE, cognostics = c("biomolecule count"),
     path = tempdir()
   )
