Answer 1

# convert a Matrix{Any} with a header row of col name strings to a DataFrame
# e.g. mat2df(["a" "b" "c"; 1 2 3; 4 5 6])

mat2df(mat) = convert(DataFrame,Dict(mat[1,:],
                     [mat[2:end,i] for i in 1:size(mat,2)]))

# convert a Matrix{Any} (mat) and a list of col name strings (headerstrings) 
# to a DataFrame, e.g. matnms2df([1 2 3;4 5 6], ["a","b","c"])

matnms2df(mat, headerstrs) = convert(DataFrame,
    Dict(zip(headerstrs,[mat[:,i] for i in 1:size(mat,2)])))
