Hello,
does anybody know about how to "send" a command or a text line from R to
another program? I have written a script in which several calculations
are
made and outputfiles (csv) are generated. Afterwards I open another
program
(Fortran) via shell.exec. This program asks for the names if the output
files and it would be quite practically if it could just adopt the file
names from the r script.
Hi Tamara,
If the succeeding program can read the name of the input file via the
command line arguments, like:
myfortranprogram -i myfile.csv
you can include the arguments in the shell call. Alternatively, you
could have R write a shell script that would execute the program with
the appropriate arguments, then call the shell script from R. Of course
if your program has to have keyboard input for the filename, you would
have to resort to magic like writing the filename into the keystroke
buffer.
