[R] Writing to a file

Here is a simple question. Is there a quicker way to write to a file several rows of data at a time rather than one line at a time? How can the code below be optimized to write several rows at a time to a file rather than one line at a time. See my slow method of write.table below:



x<-1000
for( i in 1:385420)

    (
    if(Info[i,4] > x)

       write.table (cbind(Info[i,1], Info[i,4], file="/tmp/CT.dat", append=TRUE, row.names=FALSE, col.names=FALSE)

Thanks,

-Melanie
