Could not find function "CreateChromatinAssay"

Question

[bioinformatics.girl]

I am currently running an snATAC-seq analysis and performed the following command:

chrom_assay <- CreateChromatinAssay(
   counts = counts,
   sep = c(":", ","),
   genome = 'mm10', 
   fragments = ".../fragments.tbi", 
   min.cells = 10,
   min.features = 200
)

The error that comes out is: Error in CreateChromatinAssay. Could not find function "CreateChromatinAssay"

Any ideas on what to do? I've re-installed Signac multiple times and re-started the system. No progress.

can you do this?

> grep ("CreateChromatinAssay", ls("package:Signac"), value = T)

[bioinformatics.girl]

no item called "package::Signac" on the search list

Try this:

> library(Signac)
> ls("package:Signac")
> grep ("CreateChromatinAssay", ls("package:Signac"), value = T)

It could be a disagreement between the package version and the exact command line.
