monocle2 ordercells()函数报错

问题遇到的现象和发生背景

用代码块功能插入代码，请勿粘贴截图

我想要达到的结果

HSMM <- orderCells(HSMM)
Error in if (class(projection) != "matrix") projection <- as.matrix(projection) :
the condition has length > 1
In addition: Warning message:
In graph.dfs(dp_mst, root = root_cell, neimode = "all", unreachable = FALSE, :
Argument neimode' is deprecated; use mode' instead

应该怎么解决报错呢，R包怎么修改，才能不报错？
