Adding treatment groups via metadata to Seurat object?

Question

I'd like to add metadata to 6 individual Seurat objects so that after I merge the objects into one, I can later label or split by using these identifiers. For example, I'd like to append an age group and then interval across these 6 objects. For adding an interval, I've tried using the below:

AddMetaData(control, metadata = 1hr, col.name = Interval)

However, this error will occur:

Error in .AddMetaData(object = object, metadata = metadata, col.name = col.name) : 
  object '1hr' not found

Appreciate any help, thank you!

Answer 1

You should have fed "1h" to your function call but you fed 1h instead. The latter is looking for an object with that name and as the error shows, there is no such object.
