What is the meaning of "groups" in pbmc3k.final?

[hyjforesight]

Hello all,
In https://satijalab.org/seurat/articles/visualization_vignette.html, the code is
pbmc3k.final$groups <- sample(c("group1", "group2"), size = ncol(pbmc3k.final), replace = TRUE)
I'm wondering what the meaning of c("group1", "group2") is? There is no "group1" or "group2" in pbmc3k.final.
The output is:

pbmc3k.final$groups

Hi,

The code you posted randomly assigns cells to a new meta.data column to use as an example in demonstrating plotting functions that can split or group plots by another valid meta.data variable.

e.g.,

# Split visualization to view expression by groups (replaces FeatureHeatmap)
FeaturePlot(pbmc3k.final, features = c("MS4A1", "CD79A"), split.by = "groups")

Best,
Sam
