Hi,
 
I tried to split a big file into some small files seperately by R.  I can only do that writing duplicated codes.  When I tried to write a loop, I only got one appned or destroyed exported file.   For example:
 
data1<- read.table(file = "C:\\Alice\\MBEI.txt", sep="\t", check.names=FALSE)
a<-subset(data1,select=c(V1,V2,V3))
write.table<-(a,file="C:\\Alice\\aa1.txt",quote=FALSE,row.names=FALSE,col.name=FALSE,sep="\t")
a<-subset(data1,select=c(V1,V4,V5))
write.table(a,file="C:\\Alice\\aa2.txt",quote=FALSE,row.names=FALSE,col.name=FALSE,sep="\t")
 
or
data1<- read.table(file = "C:\\Alice\\MBEI.txt", sep="\t", check.names=FALSE)
a<-data.frame(data1[,1],data1[,2],data1[,3]
write.table<-(a,file="C:\\Alice\\aa1.txt",quote=FALSE,row.names=FALSE,col.name=FALSE,sep="\t")
a<-data.frame(data1[,1],data1[,4],data1[,5]
write.table(a,file="C:\\Alice\\aa2.txt",quote=FALSE,row.names=FALSE,col.name=FALSE,sep="\t")
 
I tried to write a loop for it like :
 
 
i <- 1
while (i <3)
{
qq<-data.frame(test[,1],test[,2[i],test[,2[i]+1])
write.table(qq,file="C:\\Alice\\bb.txt",quote=FALSE,row.names=FALSE,col.name=FALSE,sep="\t")
i <- i+1;
}

But it's not right.  I tried hard to revise it but I just can't make it.  If someone can help me out here, your help is really greatly appreciated.  Thank you sooo much!
 
Best,
 
Alice
