aggregate(x, ..., force = TRUE)

## S3 method for class 'qtag.wide'
aggregate(x, ..., force = TRUE)

Arguments

x	A qtag object
...	A parameter including at least one unnamed parameter for summarising values. Additional parameters may be used for aggregating a long format.
force	Use force=FALSE to only aggregate if the object is not already summarised.

Value

A (possibly unchanged) qtag object

Examples

data(pocmaj)
pocmajqt <- as.qtag(pocmaj, id.vars=c("core", "depth"))
aggregate(pocmajqt)
aggregate(pocmajqt, mean)
aggregate(long(pocmajqt), mean, sd, length)
