So I have this data frame from a bed file called input.bed:
V1 V2 V3 V4
1 chr1 11323785 11617177 TF1
2 chr1 12645605 13926923 TF2
3 chr1 14750216 15119039 TF3
4 chr1 18102157 19080189 TF1
5 chr1 29491029 30934636 TF2
6 chr1 33716472 35395979 TF4
7 chr1 36712462 37685238 TF5
8 chr1 37838094 38031209 TF3
It's a data frame I read from a .bed file (the .bed file is tab delimited). I want to take each row and output it to a different file. Say row1 I want it to be in input1.bed , row 2 in input2.bed
This has been my attempt:
for(i in 1:nrow(input.bed))
{
file.create(paste("input",i,".bed",sep=""));
}
for(i in 1:nrow(input.bed))
{
write.table(unlist(input.bed[i,]),paste("input",i,".bed",sep=""),sep="\t");
}
For some reason the output of my files ,this is from input1.bed, is:
"V1" "chr1"
"V2" "11323785"
"V3" "11617177"
"V4" "TF1"
But I want the output to be tab delimited like this:
chr1 11323785 11617177 TF1
What am I doing wrong?
You can use just one for
loop in the following manner ( q
is your data frame)
for(i in 1:nrow(q)){
write.table(x = q[i,],
file = paste('input',i,'.bed',sep=''),
row.names = F,
col.names = F,
quote = F,
sep = '\t')
}
Basically your approach was correct, you just need to inform the function that you do not want all default behaviors (ie col/rownames, quotes).
