' @param a

' @param fallback a character value indicating what to do if all the adjusted

' values for a particular parameter-profile pair are NA. There are two

' cases. Case 1: If fallback is "NA"

' (the default), then the adjusted values are returned, even if they

' are all NA. This is a cautious approach that should yield only

' data of high quality. Case 2: if fallback is "raw", then the data in

' the adjusted columns are examined one by one. If the values in a given

' column are all NA, then the parameter's raw values are returned.

' However, if any of the values in a given adjusted column are non-NA,

' then that whole adjusted column is returned, ignoring the raw values.

' Thus, the "raw" method provides a rough estimate even for dubious

' profiles.

useAdjusted(a, fallback="NA") # default useAdjusted(a, fallback="raw")

Looking column by column:

case 1: "R" column

rval <- if (adj field exists) {
    if (all adj is NA) raw else adj
} else {
    raw
}

case 2: "D" column (this agrees with rev3)

rval <- if (adj field exists) adj else raw

case 3: "A" column

rval <- if (adj field exists) adj else raw # FIXME what to do?
