| pos2gff {ChIPseqR} | R Documentation |
Provides facility to export the location of genomic features to a GFF formatted file.
pos2gff(pos, method, feature, len, strand, score, name)
pos |
Named list with one component per chromosome giving the start position of features on that chromosome. |
method |
Entry for method field in GFF file. Recycled as necessary |
feature |
Entry for feature field in GFF file. Recycled as necessary |
len |
Length of fetures. This is used to calculate matching end positions for each start position given in |
strand |
Entry for feature field in GFF file. Recycled as necessary |
score |
Entry for feature field in GFF file. Recycled as necessary |
name |
Entry for feature field in GFF file. Recycled as necessary |
A data.frame with columns 'chromosome', 'method', 'feature', 'start',
'end', 'score', 'strand'. Writing this data frame to a text
file produces a GFF formatted file.
