ELISA

Observed signals and (for some observations) nominal
  concentrations for samples that were aliquoted to multiple assay plates,
  which were read multiple times on multiple days.   


datasets

Functions to assist in R programming, including:
- assist in developing, updating, and maintaining R and R packages ('ask', 'checkRVersion',
'getDependencies', 'keywords', 'scat'),
- calculate the logit and inverse logit transformations ('logit', 'inv.logit'),
- test if a value is missing, empty or contains only NA and NULL values ('invalid'),
- manipulate R's .Last function ('addLast'),
- define macros ('defmacro'),
- detect odd and even integers ('odd', 'even'),
- convert strings containing non-ASCII characters (like single quotes) to plain ASCII ('ASCIIfy'),
- perform a binary search ('binsearch'),
- sort strings containing both numeric and character components ('mixedsort'),
- create a factor variable from the quantiles of a continuous variable ('quantcut'),
- enumerate permutations and combinations ('combinations', 'permutation'),
- calculate and convert between fold-change and log-ratio ('foldchange',
'logratio2foldchange', 'foldchange2logratio'),
- calculate probabilities and generate random numbers from Dirichlet distributions
('rdirichlet', 'ddirichlet'),
- apply a function over adjacent subsets of a vector ('running'),
- modify the TCP\_NODELAY ('de-Nagle') flag for socket objects,
- efficient 'rbind' of data frames, even if the column names don't match ('smartbind'),
- generate significance stars from p-values ('stars.pval'),
- convert characters to/from ASCII codes.

ELISA function

a data frame with the following columns:
  <ul>
<li>PlateDayfactor. Specifies one of four physically disctinct
      96 well plates
    </li>
<li>Readfactor. The signal was read 3 times for each plate.
    </li>
<li>Descriptioncharacter. Indicates contents of sample.
    </li>
<li>Concentrationnumeric. Nominal concentration of standards (NA
      for all other samples).
    </li>
<li>Signalnumeric. Assay signal. Specifically, optical density
      (a colorimetric assay).
    </li>
</ul>
