How to extract OTU count information for the selected list of OTU in R

Question

[Bioinfonext]

Hi,

Could you please suggest to me in R, how I can extract count information across all samples for the selected list of OTU ID from the OTU table where the first column is OTU ID.

I have identified some differential OTU abundance and now for heatmap, I need the count information for these OTU across all samples.

You cannot (and should not) ask for direct answers. Show us what you have tried so far. Also, don't assume that everyone will know what an OTU table is ; rather provide a snapshot of how the table looks like. for example you can provide

summary(OTU_TABLE) or str(OTU_TABLE) or head(OTU_TABLE)
