What does "%in%" mean?

[wmseq]

Hi every one,
Is there any one knowing "%in%" meaning in the following command?

>noint = rownames (counts) %in%
c("no_feature", "ambiguous", "too_low_aQual",
"not_aligned", "alignment_not_unique")

Thanks!

Richard

Yes, that's just filtering out the last 5 lines of the output of htseq-counts. The lines are just count metrics and aren't meant for statistics.

If you just want to know about what %in% does in R, it matches. Type the following in R for more details:

help("%in%")

Small correction, technically that's just determining which lines to ignore/remove. Reading the source for DESeq2 or DEXSeq are we?

[wmseq]

Yes, for edgeR and DESeq2.
