RunUMAP报错Error in uwot(X = X, n_neighbors = n_neighbors, n_components = n_components, : n_neighb

Error in uwot(X = X, n_neighbors = n_neighbors, n_components = n_components,  : 
  n_neighbors must be smaller than the dataset size

#错误原因，没有这么多的维度，所以需要将n.neighbors设置小一点，n.neighbors默认是30

pbmc <- RunUMAP(object = pbmc, reduction = 'lsi', dims = 2:15,n.neighbors=15)#即可正常运行
