ggspaghetti function

Spaghetti Plot of mc or mcnode Object

Use ggplot to draw spaghetti plots for the [mc] or [mcnode] objects.

ggspaghetti(x, ...)

## S3 method for class 'mc'
ggspaghetti(
  x,
  griddim = NULL,
  xlab = names(x),
  ylab = "F(n)",
  main = "",
  maxlines = 100,
  ...
)

## S3 method for class 'mcnode'
ggspaghetti(
  x,
  griddim = NULL,
  xlab = names(x),
  ylab = "F(n)",
  main = "",
  which = NULL,
  maxlines = 100,
  ...
)

Arguments

• x: an mc or an mcnode object
• ...: further arguments to be passed to [ggplot2::stat_ecdf()]
• griddim: a vector of two integers, indicating the size of the grid of the graph. If NULL, the grid is calculated to produce a "nice" graph.
• xlab: vector of labels for the x-axis. If NULL, use the name of the node.
• ylab: vector of labels for the y-axis.
• main: vector of main titles of the graph
• maxlines: the maximum number of ecdf to draw.
• which: An argument used for an mcnode with multivariates. Can specify which variate plot to display. When variates are more than one, the output will be saved in a plot list by default or use the number of which variate to display.

Examples

data(ec)
EC2 <- evalmcmod(ec[[2]])
# When the input is mc object
ggspaghetti(EC2) 
# When the input is mcnode object
data(total)
# mcnode has one variate
ggspaghetti(xV) 
# This mcnode has two variates, will save two plots in a list
gplots <- ggplotmc(xVUM) #will save two plots in a list
# show the first variate plot of xVUM mcnode
gplots[[1]] 
# directly show the first variate plot of xVUM mcnode
ggspaghetti(xVUM, which = 1)
