Check whether the variables of a data frame contain imprecise observations

1	checkImprecision(data)

data

data.frame to test to apply the check onto.

A named logical vector of length ncol(data), where TRUE indicates that "|" is present in the values, which is used to indicate an imprecise observations.

This check is only reliabe for data, inheriting class "impimp". If data does not inherit class "impimp", the check is tried, but additionaly the user is notified with a warning.
