Hello,

I am currently using R to run an external program and then read the results the external program sends to the stdout which are tsv data.

When R reads the results in it converts it to to a list of strings which I then have to maniuplate with a whole slew of commands (which, figuring out how to do was a reall challenge for a newbie like myself)--see below.

Here's the code I'm using.  COMMAND runs the external program.

    rawInput= system(COMMAND,intern=TRUE);##read in tsv values
    rawInput = strsplit(rawInput, split="\t");##split elements w/in the list
                                              ##of character strings by "\t"
    rawInput = unlist(rawInput); ##unlist, making it one long vector
    mode(rawInput)="double"; ##convert from strings to double
    finalInput = data.frame(t(matrix(rawInput, nrow=6))); ##convert

Because I will be doing this 100,000 of times as part of an optimization problem, I am interested in learning a more efficient way of doing this conversion.

Any suggestions would be appreciated.


Thanks in advance.

Mike
