return first index for each unique value in a vector
I would like to efficiently find the first index of each unique value in a
very large vector.
For example, if I have a vector
A<-c(9,2,9,5)
I would like to return not only the unique values (2,5,9) but also their
first indices (2,4,1).
I tried using a for loop with which(A==unique(A)[i])[1] to find the first
index of each unique value but it is very slow.
What I am trying to do is easily

[LLVMdev] [RFC] YAML I/O
...an readable values for colors and flags, rather than just the integer value used internally. To handle that, you define conversion tables and hand them to YAMLIO. For instance:
using llvm::yaml::IO;
using llvm::yaml::Input;
using llvm::yaml::Output;
using llvm::yaml::YamlMap;
using llvm::yaml::UniqueValue;
using llvm::yaml::BitValue;
static const UniqueValue<Colors> colorConversions[] = {
{cRed, "red"},
{cBlue, "blue"},
{cGreen, "green"},
{cRed, NULL} // default value for optional keys
};
static const BitValue<uint32_t> flagConversio...
