Usage
draw.bg(start, end, ylab = "", ysub = as.character(NA), mar = c(0.2, 5, 0.2, 1),
xaxt = "s", yaxt = "n", yaxs = "r", yaxp = as.numeric(NA), ylim = c(0, 1),
cex.lab = 1, bty = "o", las = 0, xgrid = TRUE, new = FALSE, ...)Arguments
start
Single integer value, the left boundary of the window, in base pairs.
end
Single integer value, the right boundary of the window, in base pairs.
ylab
The name of the Y axis. See par.
ysub
Similar to ylab, but written on a closer line when yxat is "n". Can be NA to disable it.
mar
A numerical vector of the form "c(bottom, left, top, right)" which gives the number of lines of margin to be specified on the four sides of the plot. See par.
xaxt
Whether to plot an X axis ("s") or not ("n"). See par.
yaxt
Whether to plot an Y axis ("s") or not ("n"). If no Y axis is drawn, ysub may be used to plot a sub-title to the Y axis. See par.
yaxs
Y axis style, "r" enlarges the Y limits by 4 percents on each side for a cleaner look, "i" will not. See par.
yaxp
A numerical vector of the form "c(first, last, intervalCount)" which defines the Y axis ticks. Use NA to let R select pretty values itself. See par.
ylim
The Y axis limits as a numerical vector of the form "c(start, end)" of the plot. Note that start > end is allowed and leads to a "reversed axis". Use "NULL" to guess the axis range from the data. See plot.default.
cex.lab
The relative character size of x and y axis labels (default: 1). See par.
bty
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.
las
The direction of both X and Y axis labels: 0 for labels parallel to the axes, 1 for horizontal labels, 2 for labels perpendicular to the axes and 3 for vertical labels. See par.
xgrid
Single logical value, whether to draw a grid on X axis or not.
new
Single logical value, whether to plot on top of previous track (TRUE) or in a new track (FALSE, default).
