In pairwise: Rasch Model Parameters by Pairwise Algorithm

S3 Plotting Thustonian Thresholds with SE

Description

S3 plotting method for object of classc("pairSE","list")

Usage

## S3 method for class 'pairSE'
plot(
  x,
  ci = 2,
  sortdif = FALSE,
  ra = "auto",
  main = NULL,
  col.lines = 1:(dim(x$threshold)[2]),
  col.error = 1:(dim(x$threshold)[2]),
  type = "b",
  xlab = "items",
  ylab = "logits",
  pch = 20,
  las = 3,
  cex.axis = 0.8,
  ...
)

Arguments

x	object of classc("pairSE","list")
ci	numeric defining confidence intervall for point estimator
sortdif	logical wether to order items by difficulty
ra	either the character "auto" (default) or an numeric, defining the (logit) range for y-axis
main	see plot
col.lines	vector of colors for threshold profile lines
col.error	vector of colors for error bars
type	see plot
xlab	see plot
ylab	see plot
pch	see plot
las	see plot
cex.axis	see plot
...	other parameters passed to plot
