Hi Dear all,
I am a newbie using GRanges and related packages. Try to figure out how can I add an column of values to the GenomicRanges.
For example I get a object named as TF_peaks:
GRanges with 2000 ranges and 3 elementMetadata values
seqnames ranges strand | elementMetadata.polIIsignal elementMetadata.inputSignal elementMetadata.enrichment
<Rle> <IRanges> <Rle> | <integer> <integer> <numeric>
 chr1 [205566106, 205576720] * | 1504 4 382.2567
 chr1 [ 11890546, 11892791] * | 1140 4 347.6909
I tried to add another value to describe whether this features are overlapping with promoters(I already has this value as inpromoteres for example ).
But I can't add this value to the TF_peaks object by standard function for dataframe manipulation. I guess I am not fully understand the S4 methods. Anyone can help me out?
