Can't install package from source

[eblchen]

I want to create a renv project with a downgraded version of Seurat and SeuratObject but when I try to install the package from source it outputs the following error.

> install.packages("Seurat_4.0.5.tar.gz", repos = NULL, type = "source") Error: failed to resolve remote 'Seurat_4.0.5.tar.gz' -- failed to parse remote spec 'Seurat_4.0.5.tar.gz'

Seurat_4.0.5.tar.gz

Try:

utils::install.packages("Seurat_4.0.5.tar.gz", repos = NULL, type = "source")
