I am trying to use a meta data set with information about some repetative
analysis that I have to do for a variables measured on multiple occasions. 

I think the best way to explain the problem is by using a simplified
example. So here goes:

I have a data frame called "meta" say with the following content:

Test  Min  Max  Low  High
APS    0    40  -10   10
TPP    0   120   -8    8
NOS    0    25  -15   12
... etc ...

I want to create an object based on each of the Test names, for example:

cADS <- function(ADS1, min=0, max=40; low=-10, high=10)
cTPP <- function(TPP1, 0, 120, -8, 8)
cNOS <- function(NOS1, 0, 25, -15, 12)
.. etc ...

where ADS1, TPP1, NOS1, etc. are columns from a second data frame, say,
"study".

So in summary how do I create a variable based on the entries in "meta"
(e.g. from 'APS' I want to create 'cAPS') using a column in another data
frame again based on the entry in "meta" (eg, ADS0, ADS12, etc...).

I hope that this explains my problem clearly, if not please let me know.

Thanks for your help in advance,
Saghir


Before I get flamed for what might be a simple solution to a previously
discussed problem on this list or addressed in the FAQs, I have tried
extensively (for 3 days now!!!!) to find a solution myself. None of my
colleagues can help as I am their "R help" most of the time!!! I have tried
various helps terms on google with and without "r-help", looked at various
Splus books, and I even looked at all the functions on HTML version of R
help - I still have no idea what I am looking for. In the past I have
succeed in doing such things in Stata and SAS.
