Check whether the variables of a data frame contain imprecise observations
data.frame to test to apply the check onto.
A named logical vector of length
TRUE indicates that
"|" is present in the
values, which is used to indicate an imprecise observations.
This check is only reliabe for
data does not inherit class
"impimp", the check is tried, but additionaly the
user is notified with a warning.
