Conicsmat throws an error for filterMatrix()

[biobug16]

Hi I am trying to run conicsmat and everytime I get an error at filterMatrix() My code is

gene_pos=getGenePositions(rownames(log2mat)) log2mat1=filterMatrix(log2mat,gene_pos[,"hgnc_symbol"],minCells=5)

Error in UseMethod("filter_") : 
  no applicable method for 'filter_' applied to an object of class "c('tbl_SQLiteConnection', 'tbl_dbi', 'tbl_sql', 'tbl_lazy', 'tbl')"
Calls: getGenePositions ... .sql_get_resource_table -> tryCatch -> tryCatchList -> %>% -> filter_

Kindly please guide how can I overcome this issue.

Thanks
