Description

The the difference (

Usage

targeting_motive_plot(pwm, xaxis = TRUE, yaxis = TRUE, xfontsize = 15,
  yfontsize = 15, xlim)

Arguments

pwm	Result of the function hotspot().
xaxis	Accept TRUE/FALSE parameter. TRUE draw X-axis.
yaxis	Accept TRUE/FALSE parameter. TRUE draw Y-axis.
xfontsize	The plot size of the X-axis.
yfontsize	The plot size of the Y-axis.
xlim	Limit of the drowed Y-axis.

Value

Output is plot the sequence logos around the mutation.

Note

The Function are based on functions from package segLogo.
