pathwayRes {phoenics}

Class pathwayRes

Description

S3 class for pathway differential analysis results

Usage

## S3 method for class 'pathwayRes'
summary(object, ...)

## S3 method for class 'pathwayRes'
print(x, ...)

## S3 method for class 'pathwayRes'
plot(
  x,
  ...,
  pathway_id = NULL,
  plot = c("eig", "var", "ind"),
  habillage = "none"
)

head(object)

extract(object, pathway_id)

adjust_pval(object, method = p.adjust.methods, n = length(object))

Arguments

object, x

object of class pathwayRes

...

not used

pathway_id

a character string or vector of pathway codes or names

plot

a character string indicating the type of plot to return. Default to "eig" (the screegraph of the PCA is displayed)

habillage

a character string indicating the column of the design used to color the individuals. Only used when plot = "ind". Default to "none" (no color)

method

a character string indicating the correction method to be used for multiple testing correction (authorized values are those of p.adjust.methods)

n

number of comparisons for multiple testing correction

Methods for the class pathwayRes

Value

The function extract returns an object of class pathwayRes which is a list of pathway results, containing only the pathways in pathway_id.

The function adjust_pval returns a data.frame with pathways in rows and the following information in columns:

pathway_name

name of the pathway

pathway_code

pathway code (identifier)

Fixed_effect

tested effect

pval

raw p-value of the pathway

adjusted_pval

adjusted p-value of the pathway

Examples

quantif <- from_ASICS_to_PHOENICS(quantif)
out_test <- test_pathway(quantif, design, pathways, 
                         fixed = c("Age", "Treatment"), random = "Mouse", 
                         npc = 2, model = "blmer")
