Hi All,
I am using below code to execute a batch file on server to get me data from
an API
it looks like:
shell.exec('<<path name>>\\file.bat')
#do next step
The problem is that this function shell.exec doesn't wait for the batch
file to execute completely and jumps to next line of code.
Any ideas how can I hold R to go for next line of code until and unless
batch file has completed its execution.
Many thanks.
P.S: I tried to use shell() but it says could not find function shell

For future reference, this kind of question should usually be accompanied by information about your OS such as the sessionInfo function returns... but in this case just read about the wait argument to ?system2. -- Sent from my phone.
