This function draws a slice of a track content, with a distinct vertical bar for each track element.
draw.hist(slice, start, end, column = "value", fillColor = "#666666",
border = "#666666", cex.lab = 1, origin = 0, bty = "o", fg = "#000000",
ylim = NA, ...)
A data.frame
holding the data to plot, with elements in rows and data in columns.
Single integer value, the left boundary of the window, in base pairs.
Single integer value, the right boundary of the window, in base pairs.
Single character value, the name of the slice
column to use for bar heights.
The color to fill vertical bars with (as a name, an integer or an hexadecimal character description). It can alternatively be a function without argument, which returns a vector of as many colors as slice
has rows. It can make direct variable call to any argument described on this page (including custom arguments passed via "...").
The color to use for box borders (as a name, an integer or an hexadecimal character description). It can alternatively be a function without argument, which returns a vector of as many colors as slice
has rows. It can make direct variable call to any argument described on this page (including custom arguments passed via "..."). Special values NA
and "fillColor"
can also be used to disable borders or use fillColor
respectively.
The relative character size of x and y axis labels (default: 1). See par
.
Single numeric value, the Y value of the horizontal side common to all boxes. Can also be the name of a slice
numeric column to use as a segment-specific origin.
A character string which determined the type of box which is drawn about plots. If bty is one of "o" (the default), "l", "7", "c", "u", or "]" the resulting box resembles the corresponding upper case letter. A value of "n" suppresses the box. See par
.
Single character value, defining the color of the foreground (axes, labels...) as an english name or a hexadecimal code. Similar to par
's argument but not relying on it.
Numeric vector of length two, defining the Y axis boundaries. Any or both of them can be NA, meaning the missing boundary will be inferred from the data to plot.
