conquestr has two main types of plots. The first is plots based on
plot command in ACER
ConQuest. These plots are done using the generic function
conquestr::plotRout The second is more general plots,
usually of the inputs or outputs of IRT estimate.
library(conquestr) <- ConQuestRout() myRout#> no rout file provided, loading the example rout file instead plotRout(myRout)
You can plot an arbitrary information function against a distribution of students - a so called information Wright map.
<- runif(10, -1, 1) myItems<- rnorm(500, 1, 1) myPersonsinformationWrightMap(myItems = myItems, myAbilities = myPersons, minTheta = -6, maxTheta = 6)
