netresponse (version 1.32.2)

sample2response: sample2response

Description

Probabilistic sample-response assignments for given subnet.

Usage

sample2response(model, subnet.id, mode = "soft")

Arguments

model

Result from NetResponse (detect.responses function).

subnet.id

Subnet identifier. A natural number which specifies one of the subnetworks within the 'model' object.

mode

soft: gives samples x responses probabilistic assignment matrix; hard: gives the most likely response for each sample

Value

• A matrix of probabilities. Sample-response assignments for given subnet, listing the probability of each response, given a sample.

Examples

#data( toydata )        # Load toy data set
#D    <- toydata$emat   # Response matrix (for example, gene expression)
#netw <- toydata$netw   # Network

# Detect network responses
#model <- detect.responses(D, netw, verbose = FALSE)

# Assign samples to responses (soft, probabilistic assignments sum to 1)
#response.probabilities <- sample2response(model, subnet.id = "Subnet-1")
