Here it is late, so of course I forgive you the typo! :) But many thanks
for the TIP! :)
However, it doesn't seem to work here. My problem was that my matrix was
composed by SubString{ASCIIString}. So, if I call typeof(myportfolio[1]) I
get:
julia> typeof(myportfolio[1])
SubString{ASCIIString}
And the same if I call typeof(myportfolio[1,1]):
julia> typeof(myportfolio[1,1])
SubString{ASCIIString}
Could you please send the result of typeof(myportfolio[1]) in your example?
I suppose it would be an ASCIIString.
Seth's suggestion worked fine for me. To use a cast to ASCIIString to
convert myportfolio[1], like this:
julia> typeof(ASCIIString(myportfolio[1]))
ASCIIString
But thanks anyway!
Best,
Charles
