# S3 method for edsurvey.data.frame
dim(x)For an edsurvey.data.frame, returns a
numeric vector of length two, with the first element being the number
of rows and the second element being the number of columns.
For an edsurvey.data.frame.list, returns a list of length
two, where the first element is named nrow and is a
numeric vector containing the number of rows for each element of the
edsurvey.data.frame.list. The second element is named
ncol and is the number of columns for each element.
This is done so that the nrow and ncol functions
return meaningful results, even if nonstandard.
