Description

  retval=list(indx=vector("numeric",0),element=NULL,value=NA,depth=0))

Arguments

x

The output of brkdn.num.

errbars

Whether to include the second row of x (the dispersion) in the calculation of the maximum value.

retval

A list containing useful information about the list.

brkdnCrawler crawls a list produced by brkdn.num and returns the information needed by hierobarp.

Examples

test.df<-data.frame(Age=rnorm(100,25,10),
  Sex=sample(c("M","F"),100,TRUE),
  Marital=sample(c("M","X","S","W"),100,TRUE),
  Employ=sample(c("FT","PT","NO"),100,TRUE))
 test.brk<-hierobrk(formula=Age~Sex+Marital+Employ,data=test.df)
 brkdnCrawler(test.brk)
