我需要计算单个途径重复进入数据帧的次数，例如：hsa04014 = 5，hsa04012 = 20等。有人可以帮助我吗？
我的数据结构是：
structure(list(Hugo_Symbol = c("ABL1", "ACACA", "ACOX1", "ACTA2",
"ACTB", "ACVR1"), Entrez_Gene_Id = c(25L, 31L, 51L, 59L, 60L,
90L), Pathways = c("hsa04014,hsa04012,hsa04110,hsa04722,hsa05200",
"hsa04910,hsa04922", "hsa04024,hsa04520", "hsa04270", "hsa04014,hsa04390,hsa04510,hsa04520,hsa04530,hsa04921,hsa04919,hsa05200",
"hsa04350")), row.names = c(NA, -6L), class = c("grouped_df",
"tbl_df", "tbl", "data.frame"), vars = "Hugo_Symbol", drop = TRUE, indices = list(
0L, 1L, 2L, 3L, 4L, 5L), group_sizes = c(1L, 1L, 1L, 1L,
1L, 1L), biggest_group_size = 1L, labels = structure(list(Hugo_Symbol = c("ABL1",
"ACACA", "ACOX1", "ACTA2", "ACTB", "ACVR1")), row.names = c(NA,
-6L), class = "data.frame", vars = "Hugo_Symbol", drop = TRUE))
