plotmatrix {LSD}

Visualize two-dimensional data

Description

Plot the rows of a matrix as lines along the cols.

Usage

plotmatrix(
  input,
  xlim = NULL,
  ylim = NULL,
  xlab = "",
  ylab = "",
  main = "plotmatrix",
  type = "l",
  lwd = 2,
  at = NULL,
  xlabels = NULL,
  ltys = NULL,
  add = FALSE,
  cols = NULL,
  ...
)

Arguments

input

a matrix with numerical entries.

xlim

x limits, standard graphics parameter.

ylim

y limits, standard graphics parameter.

xlab

x lab, standard graphics parameter.

ylab

y lab, standard graphics parameter.

main

title of the plot, standard graphics parameter.

type

what 'type' of plot should be drawn (to be passed to points).

lwd

a positive number giving the line width.

at

a integer vector containing the x-positions corresponding to the columns of 'input'.

xlabels

a character vector containing labels for the x-axis.

ltys

a numeric vector giving the line types for each row of 'input'.

add

logical: if TRUE (FALSE by default), lines are added to existing plot.

cols

a character vector of R build-in colors.

...

additional parameters to be passed to points and plot.

Examples

len = 20
x = sin(seq(0,2*pi,length=len*2))
fun = function(){n=sample(1:len,1); return(x[n:(n+len-1)])}
input = t(replicate(7,fun(),simplify=TRUE))
input = input + rnorm(length(input))/2
