[R] change the name of file

2006-07-24 Thread Robert Mcfadden

Dear R Users,
Is it possible to make file names dependent on a changing variable?
For instance. I generate random numbers in a loop and at each iteration I
want data to write to file (I do not want to write everything in one file
using 'append'):

for (i in 1:50){
x-matrix(runif(100, min=0,max=1),nrow=5,ncol=20)
Write(t(x),file=Data_i.txt,ncolumns=5,sep=\t) 
}   

Of course file name Data_i.txt will be the same for changing i,
unfortunately. 

Any suggestion would be appreciate
Robert

Do you mean write.table instead of Write() ? Try 

 fn - paste(Data_, i, .txt, sep=)
 write.table( t(x), file=fn, sep=\t )

Great, little change and it works. Thank you.
Look
 

for (i in 1:50){
x-matrix(runif(100, min=0,max=1),nrow=5,ncol=20)
write(t(x),file=paste(data_,i,.txt,sep=),ncolumns=5,sep=\t) 
}

 i think file=paste(data_, i,txt,sep=)
 should work but someone else will probably
 have a better solution. if you try my idesa,
 check it because i haven't tested it.

Dear Robert,

maybe (!) the following might do the job:

for (i in 1:50){
x-matrix(runif(100, min=0,max=1),nrow=5,ncol=20)
Write(t(x),file=paste(Data_ i .txt, sep=),ncolumns=5,sep=\t)
}

Hope it really does...
Thilo
