getWM {edl}

Retrieve all cues from a vector of text strings.

Description

Retrieve all cues from a vector of text strings.

Usage

getWM(wmlist, event = NULL)

Arguments

wmlist

A list with weightmatrices for each learning event, generated by RWlearning.

event

Numeric: for which event to return the weight matrix. Defaults to NULL, which wil return the last weight matrix.

Value

A matrix with connection weights between cues (rows) and outcomes.

Examples

# load example data:
data(dat)

# add obligatory columns Cues, Outcomes, and Frequency:
dat$Cues <- paste("BG", dat$Shape, dat$Color, sep="_")
dat$Outcomes <- dat$Category
dat$Frequency <- dat$Frequency1
head(dat)
dim(dat)

# now use createTrainingData to sample from the specified frequencies: 
train <- createTrainingData(dat)

# this training data can actually be used train network:
wm <- RWlearning(train)

# final weight matrix:
getWM(wm)
# ... which is the same as:
wm[[length(wm)]]
# 25th learning event:
getWM(wm, event=25)
# ... which is the same as:
wm[[25]]
