Details

This function is a low-level plotting function (using rect, internally).

Examples

# read data and create DLData object
seqs <- read.table(system.file("extdata", "cjun.txt", package = "DepLogo"),  
   stringsAsFactors = FALSE)
data <- DLData(sequences = seqs[, 1],weights = log1p(seqs[, 2]) )

# create high-level plot
plot(NULL, xlim = c(1, ncol(data$data) - 1), ylim = c(0, nrow(data$data)), 
    ylab = nrow(data$data), axes = FALSE)
# and add deprects and axis
deprects(data, yoff = nrow(data$data))
axis(1)
