Re: [R] change the name of file
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

Re: [R] change the name of file
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")
}

?paste, e.g. paste("Data_", i, ".txt", sep="")

Re: [R] change the name of file
Do you mean write.table instead of Write() ? Try
fn <- paste("Data_", i, ".txt", sep="")
write.table( t(x), file=fn, sep="\t" )

Re: [R] change the name of file
Use paste("Data_",i, sep="")

[R] change the name of file
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
