Remove column from Seurat metadata

Question

[gorizwango]

How can I remove a particular entry in my metadata table in Seurat? Like I have a dataframe named seu which has different objects assessed through @, and in each object we have several entries which can assessed through $.

[e-mail][["percent.globin"]]

So, if I need to remove an entry inside metadata object, how can I do that?

Try setting it to NULL.

seu$percent.globin <- NULL

Just in case someone reaches this post with the same question but they need to remove several columns with a particular pattern (e.g.: RNA_snn_res.0.1, RNA_snn_res.0.2, RNA_snn_res.0.3...), you can use this code:

[e-mail] <- [e-mail][, !grepl("RNA_snn_res", colnames([e-mail]))]
