Description Usage Arguments Details Value Author(s) See Also Examples

A very simple little routine to generate dbh class limits and the midpoint of the range for each class.

dbhClassLimits(dbh.low = 1,
               dbh.up = 20,
               dbh.width = 1,
               forceIntegerWidth = TRUE,
               adjustLowest = NULL,
               classNames = c('dbh.low','dbh.mid','dbh.hi'),
               runQuiet = TRUE,
               ... )

`dbh.low`	The lower midpoint dbh.
`dbh.up`	The upper midpoint dbh.
`dbh.width`	The DBH class width (should be integer) for all classes, except possibly the first.
`forceIntegerWidth`	TRUE: dbh class widths must be integer; FALSE: can be real.
`classNames`	a vector of length 3 for the labels of the data frame returned; always in the form lower, mid and upper.
`adjustLowest`	NULL, NA, or <=0 means no adjustment; other positive means to subtract this amount from the lower bound of the smallest class.
`runQuiet`	TRUE: no feedback; FALSE: some feedback.
`...`	Arguments to be passed on or gobbled up.

There's really not much too this. I just put it into a package because I end up re-inventing it so much over the year and find it handy to now have to call upon.

A data frame with the lower, mid, and upper limts for all diameter classes as request.
