I have given the code that the rules are generated.I would like to create an item frequency histogram plot but ıt didn't work. 

library(arules)
library(arulesViz)
library(rattle)

x <- read.table("C:/Users/toshıba pc/Desktop/Kitap2.csv", header = TRUE, sep = ";")
y <- as.matrix(x)

rules <- apriori(y, parameter = list(supp = 0.1, conf = 0.8))

itemFrequencyPlot(rules, support = 0.1, cex.names = 0.8)

Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘itemFrequencyPlot’ for signature ‘"rules"’

itemFrequencyPlot is not defined for rules. You can use

itemFrequencyPlot(items(rules))

to get the frequency of the items in the rules, but I am not sure that this will give you the results you want.
