Examples

# NOT RUN {
data(images8By8)
data(images10By10)

# Create tableMatrix from images8By8 and images10By10
TM <- tableMatrix(list(images8By8, images10By10), list(1:3, 1:3),
list(4:ncol(images8By8),4:ncol(images10By10)))

# Row 91 in tab(TM) corresponds to second matrix, first row 
row <- getRow(TM, 91)

# Row 91 in tab(TM) corresponds to second matrix, first row 
getRow(TM, repo=c(2,1))

# Change matrix row corresponding to row 91 in tab(TM) 
TM <- setRow(TM, rep(2,length(row)), 91)
getRow(TM, 91)

# }
