[R] question about "system" command

[Austin, Matt]

Something like this.

See ?formatC, ?paste

for (i in 1:100)
{
    system(paste("C:\\Progra~1\\DOSPROGRAM\\RUN.exe input",
                  formatC(i, digits=2, flag='0'),
                  '.dat',
                  sep=''))
}

Subject: [R] question about "system" command


Hi R Users
I am going to write a very short script for my small pilot simulation study.
I need to call a DOS program with different input data files in the middle 
of for loop.
There are 100 input data files (e.g., input001.dat, input002.dat, .... , 
input100.dat)

for (1 in i :100)
{
    system('"C:\\Program Files\\DOSPROGRAM\\RUN.exe" input001.dat')
}

I like to change the input data file name as for loop runs. How can I do 
that ?

Thanks in advance

TM
