Error in if (tolower(filter) == "novar") { : missing value where TRUE/FALSE needed

[Moonerss]

Thanks for this awesome package.

When I use it with a dataset contain about 190,000 cells，I got an error：

Error in if (tolower(filter) == "novar") { : missing value where TRUE/FALSE needed

I think it maybe caused by the judgment condition not matching the condition content when run applyMicroClustering in poolCells.

## code in poolCells
if (is.null(object@params$latentSpace[["projectionGenes"]])){
        filterInput <- object@params$latentSpace$projectionGenesMethod
    } else {
        filterInput <- object@params$latentSpace$projectionGenes
    }

    if (length(object@Pools) == 0) {
        pools <- applyMicroClustering(
            object@exprData,
            cellsPerPartition = object@params$micropooling$cellsPerPartition,
            filterInput = filterInput,
            filterThreshold = object@params$latentSpace$threshold,
            latentSpace = object@LatentSpace,
            K = object@params$numNeighbors)

        object@Pools <- pools
    }

Below is the code I run：

> vis <- Vision(cpm_mat, signatures = pathway_gmt, meta = cpm_seurat@meta.data)
Loading data from /public/home/ezhao/qian_lab/raw_data/myself/analysis/metabolism/data/raw_data/latest_main_metabolism_pathway.gmt ...

Using 17620/17638 genes detected in 0.10% of cells for signature analysis.
See the `sig_gene_threshold` input to change this behavior.

Over 100000 input cells detected.  Enabling micropooling with max 10 cells per pool.
