trelli_panel_by {pmartR}

Set the "panel_by" variable for a trelliData object

Description

Allows for grouping omics or stats data for downstream plotting and cognostic functions

Usage

trelli_panel_by(trelliData, panel)

Arguments

trelliData

A trelliscope data object made by as.trelliData or as.trelliData.edata. Required.

panel

The name of a column in trelliData to panel the data by. Required.

Value

A trelliData object with attributes "panel_by_omics" or "panel_by_stat" to determine which columns to divide the data by.

# Group the data by condition

# Apply the IMD ANOVA filter

                             "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)

## "panel_by" with an edata file. 
trelli_panel_by(trelliData = trelliData1, panel = "Peptide")

## "panel_by" with trelliData containing omicsData. 
## Generate trelliData2 using the example code for as.trelliData

## "panel_by" with trelliData containing statRes. 
## Generate trelliData3 using the example code for as.trelliData
trelli_panel_by(trelliData = trelliData3, panel = "Peptide")

## "panel_by" with trelliData containing both omicsData and statRes. 
## Generate trelliData4 using the example code for as.trelliData
