deprects: Rectangles of averaged colors
In Jstacs/DepLogo: Dependency Logo

Description Usage Arguments Details Value Author(s) Examples

Plots a representation of a set of sequences by rectangles of (scaled) averaged color values of the symbols at each position

1	deprects(part, yoff, ic.scale = TRUE)

`part`	the set of sequences as DLData object
`yoff`	the offset in y-direction within the current plot
`ic.scale`	if `TRUE`, alpha values of colors will be assigned based on "information content" of the distribution at each position

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

the vertical (y) offset after this plot

# 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)
