The answer, which came from Steve Ellison (thanks!) is to note that "stats" is the only bit of the "z" argument to bxp that has to be present, so given a data file with columns year,mean,median,centiles, something like this works: # transform data so the rows are the various centiles in order # there's probably a more elegant approach! bsr <- matrix(allobs[,c(4,5,3,6,7)],nrow=5,byrow=TRUE) # column 1 is the year, which is our factor bsbox <- list( stats=bsr,names=allobs$V1) bxp(bsbox,xlab="Year",ylab="Number of cattle per batch") I thought I'd follow-up so the answer to my question will be in the archives.
