plotGVF {FunctanSNP}

Plot the genetic variant function

Description

Plot the estimated genetic variant function obtained by SNPgvf or a given functional data object(s).

Usage

plotGVF(x, y = NULL, Lfdobj = 0, href = TRUE, titles = NULL,
  xlim = NULL, ylim = NULL, xlab = NULL, ylab = NULL,
  ask = FALSE, nx = NULL, axes = NULL)

Arguments

x

functional data object(s) to be plotted, such as the estimated genetic variant function obtained by SNPgvf.

y

sequence of points at which to evaluate the functions 'x' and plot on the horizontal axis. Defaults to seq(rangex[1], rangex[2], length = nx).

Lfdobj

either a nonnegative integer or a linear differential operator object. If present, the derivative or the value of applying the operator is plotted rather than the functions themselves.

href

a logical variable: If TRUE, add a horizontal reference line at 0.

titles

a vector of strings for identifying curves

xlim

a vector of length 2 containing axis limits for the horizontal axis.

ylim

a vector of length 2 containing axis limits for the vertical axis.

xlab

a label for the horizontal axis.

ylab

a label for the vertical axis.

ask

a logical value: If TRUE, each curve is shown separately, and the plot advances with a mouse click

nx

the number of points to use to define the plot. The default is usually enough, but for a highly variable function more may be required.

axes

Either a logical or a list or NULL.

• logical whether axes should be drawn on the plot

• list a list used to create custom axes used to create axes via x$axes[[1]] and x$axes[-1]. The primary example of this uses list("axesIntervals", ...)

Value

plot the estimated genetic variant function.
