vlookup: Vectorized lookup
In drknexus/repsych: Package for reproducible psychological research

This function does a vectorized lookup on a data.frame. That is, each individual row is matched with a particular column.

`df`	A data.frame
`rowValues`	A vector of the row values to lookup, matched element by element with colValues
`colValues`	A vector of the column values to lookup, matched element by element with rowValues

A vector from df[x,y] where x and y are pulled in matched pairs

1 2	df.eg <- as.data.frame(matrix(1:100,10,10)) vlookup(df.eg,c(1:6,6:1),rep(c("V1","V2"),each=6))
