>    Hi,
>    I have a mapping M consisting of a vector of bin centers (say 0.01, 0.02,
>    0.03 ..., 1) with associated values (say "red", "orange", "yellow", ...),
>    stored as a 2-column matrix with column 1 the bin center and column 2 the
>    value.
>    I also have a vector D of data (say 0.9056, 0.4118,  0.2162,  ...).
>    I want to map each datum in D to the value associated with its bin in M (say
>    0.0111-> red, 0.0198 -> orange, ...) .
>    Does R have a built-in function for this?
>    Thanks for tips/suggestions.
