Get and set cell-level meta data

# S3 method for Seurat
$(x, i)

# S3 method for Seurat
$(x, i, ...) <- value

# S4 method for Seurat,character,missing,data.frame
[[(x, i, j, ...) <- value

# S4 method for Seurat,missing,missing,data.frame
[[(x, i, j, ...) <- value

# S4 method for Seurat,character,missing,factor
[[(x, i, j, ...) <- value

# S4 method for Seurat,character,missing,list
[[(x, i, j, ...) <- value

# S4 method for Seurat,missing,missing,list
[[(x, i, j, ...) <- value

# S4 method for Seurat,character,missing,vector
[[(x, i, j, ...) <- value

Arguments

x

A Seurat object

i

Name of cell-level meta data

...

Ignored

value

A vector to add as cell-level meta data

j

Ignored

Value

$: Metadata column i for object x; note: unlike [[, $ drops the shape of the metadata to return a vector instead of a data frame

$<-: x with metadata value saved as i
