Usage

inspect(x, ...)

Arguments

`x`	a set of associations or transactions or an itemMatrix.

inspect(rules[1000:1001])
inspect(rules[1000:1001], ruleSep = "~~>", itemSep = " + ", setStart = "", setEnd = "", 
  linebreak = FALSE)

## to get rules in readable format, use coercion or DATAFRAME with additional parameters.
as(rules[1000:1001], "data.frame")
DATAFRAME(rules[1000:1001])
DATAFRAME(rules[1000:1001], separate = TRUE, setStart = "", setEnd = "")
