what: the type of 'what' gives the type of data to be read.
It seems to me that I had read somewhere (maybe on the mailing list archives), that 'what' was supposed to be a sort of example of the kind of data you had to read... so I put a character string because I wanted the data to be read as character because I had a column of factors. I know this is not a great way to do it (better have a matrix made up of nubers only, instead of having to subsequently convert columns of character strings to number) but I wanted to do a quick test without having to rearrange my file.
