[R] passing args to R CMD BATCH in win 2000
Hello and sorry to bother. Please help. I searched the archives but could not find out why --args is being ignored on Windows 2000. I try R CMD BATCH --slave 11.R 11.Rout --args 12 and 11.R has x=commandArgs(trail=T) print(x) a=x[length(x)] write.csv(a,file=13.out) q(no) the argument is not passed to the R process. 11.Rout only shows processing time and 13.out does not have the value.

Re: [R] help with tryCatch
Henrik,
Please, stay with me.
there is a problem with the way tryCatch processes statements and that
is exactly what the help file does not describe at all. I am trying
catch=function(vec){
ans=NULL;err=NULL;
for (i in vec) {
tryCatch({
source(i);
ans=c(ans,i);
cat(ans, from try);
},
error=function(er){
cat(i, from catch\n);
err=c(err,i);
}
)
}
ret=list(ans=ans,err=err)
ret
}
v=c(gdhfdh,hdhdfjh) #non-existent files
ret=catch(v) # err is NULL and none of the statements in that block is
executed ??
below is a Java example that executes the catch block as it should. How
can I achieve the same in R?
***
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Vector;
public class ReadFiles {
public static void main(String[] args) {
String[] files={asdf,qwert};
Vector err=new Vector();
FileReader inputStream = null;
for (int j=0;j2;j++){
try {
inputStream = new FileReader(files[j]);
int c;
while ((c = inputStream.read()) != -1) {}
} catch(IOException e){
err.add(j,files[j]); // this statement executes!
} finally {
if (inputStream != null) {
inputStream.close(); // IO not encapsulated here,
but declared in main throws. pls ignore since source(arg) in R takes
care of closing.
}
}
}
for (Object j:err){
System.out.println(j);
}
}
}

To be more precise, put the tryCatch() only around the code causing
the problem, i.e. around source(). /H

Henrik,
thank you for the reference. Can you please tell me why the following
does not work?
vec=c(hdfhjfd,jdhfhjfg)# non-existent file names
catch=function(vec){

catch(vec) # throws an error after the first file and stops there
while
I want it to go through the list and accumulate the nonexistent
filenames in err.
Thank you

Henrik,
I had looked at tryCatch before posting the question and asked the
question because the help file was not adequate for me. Could
you pls
provide a sample code of
try{ try code}
catch(error){catch code}
let's say you have a vector of local file names and want to
source them
encapsulating in a tryCatch to avoid the skipping of all good
file names
after a bad file name.
thank you

I know the code above does not work, but it conveys the idea.
tryCatch
help page says it is similar to Java try-catch, but I know
how to
do a
try-catch in Java and still can't do it in R.
Thank you very much.
