plotClustersMean function

Plotting Clustered Mean Vectors

Function plotClustersMean produces a plot of multiple panels. Each panel displays for a inferred cluster the mean vectors of items allocated to this cluster, as well as the inferred cluster mean vector. See figures in Fu, Russell, Bray and Tavare.

plotClustersMean(data, data.summary, 
    SKIP, nTime = length(times), times = 1:nTime, ...)

Arguments

• data: An $N \times JR$ matrix of continuous values, or a data frame containing such a matrix. $N$ is the number if items, $J$ the number of time points (or experimental conditions) and $R$ the number of replicates. Each row contains values for Replicates 1 through $R$ under Condition 1, values for Replicates 1 through $R$ under Condition 2, and so on.
• data.summary: The list generated from summaryDIRECT that contains processed posterior estimates.
• SKIP: Number of columns in data to be skipped when processing the data.
• nTime: Number of time points (or experimental conditions).
• times: An integer vector of length nTime, indicating times (or experimental conditions).
• ...: Additional arguments for plot.

Returns

None.
