plot-methods: Plot Methods for Classification and Scores s4 objects
In classify: Classification Accuracy and Consistency under IRT models.

Produces various plots of score distributions and classification statistics.

## S3 method for class 'scores'
plot(x, type = c("exp","cond","qq"),alpha = 0.05, ...)
## S3 method for class 'classification'
plot(x, type = c("acc", "kappa", "density"), ...)

`x`	an object inheriting either from class `scores` or class `classification`
`type`	the type of plot: "exp": Expected summed scores compared to observed "cond": Conditional summed scores compared to observed "qq": QQ plot of conditional summed scores compared to observed "acc": Classification accuracy "kappa": Kappa "density" Density
`alpha`	Alpha value for points on qq plot.
`...`	extra graphical parameters
