acf() plots of a data.frame: what meaning?
Hello,
what is the meaning of the plots of an acf()-plot,
when using a data frame as argument?
The result is NOT obvious for me.
There are combinations of the columns of a dataframe in the reulting
plot.
But an acf() is just defined for onyl one time-sreies.
So what do the plots mean? I did not found a description in the
help-page.
Ciao,
Oliver
