Renaming data in a Seurat object metadata

I have a seurat object "gunion.data". The metadata for gunion.data@meta.data$orig.ident is either "control, "ischemia", "synIRI" or "alloIRI". I would like to change ""synIRI" and "alloIRI" into "other".

I tried this gunion.data@meta.data$orig.ident["alloIRI"] <- "other"

but it gave me an error: Error in $<-.data.frame(tmp, orig.ident, value = c("control", "control", : replacement has 26933 rows, data has 26932

How should I format the code to change all "alloIRI" and "synIRI" in the data into "other"?

What you want to do is rename an Ident. The below should work once you've changed your idents to 'orig.ident'.

Idents(gunion.data) <- 'orig.ident'
gunion.data <- RenameIdents(object = gunion.data, `synIRI` = "other", `alloIRI` = "other")

Idents(gunion.data) #to confirm the change has happened.

I would suggest you also have a look at the Seurat Essential commands, found here.
