exporting the results of edgeR into a text file using R
I have done differential expression analysis using edgeR. now I am trying to export its output ,which looks like the small example, into a text file. I used this code : wirte.table(ltr, file="genes.txt") to export but did not work.
small example:
> topTags(lrt)
Coefficient: TissueT
gene_ID logFC logCPM LR PValue FDR

Define "did not work".
gave this error:
Please try to understand what object that stores the information regarding the DEGs and then try to get the output. You need to learn what are the typical structure of the objects that are defined in your edgeR analysis. Then only you can able to clearly exploit it.
