InstallData("stxBrain") is not working

[gakabani]

Hi all, I am new to this site and I am currently learning from your examples.
I am following the example "Analysis, visualization, and integration of spatial datasets with Seurat" and I was able to install all the libraries. However, following the instructions, I found the following error in the line

InstallData("stxBrain")
trying URL 'http://seurat.nygenome.org/src/contrib/stxBrain.SeuratData_0.1.1.tar.gz'
Content type 'application/octet-stream' length 110346050 bytes (105.2 MB)

downloaded 73.7 MB

Error in download.file(url, destfile, method, mode = "wb", ...) :
download from 'http://seurat.nygenome.org/src/contrib/stxBrain.SeuratData_0.1.1.tar.gz' failed
In addition: There were 38 warnings (use warnings() to see them)
Warning in download.packages(pkgs, destdir = tmpd, available = available, :
download of package ‘stxBrain.SeuratData’ failed
Error in loadNamespace(name) :
there is no package called ‘stxBrain.SeuratData’
However, when I execute the line

InstallData("ssHippo")

it was executed with no errors.

Am I missing something?

Any help will be appreciated
