Question

我有一个以下格式的文本文件：

   "C1","name1","type1": 2
   "C1","name2","type4": 6
   "C2","name1","type2": 1
   "C1","name3","type1": 10

我试过了：

   db<- read.table("myfile.txt")

但是这会将文件存储为两列，并将值存储为＆＃34; name1＆＃34;，我也尝试过：

  db<- read.csv("myfile.txt", header= FALSE)

但是这会将最后两列存储为一列：

    C1   name1     type1:2
    C1   name2     type4:6
    C2   name1     type2:1
    C1   name3     type1:10

如何将最后两列存储为两个单独的列

    C1   name1     type1  2
    C1   name2     type4  6
    C2   name1     type2  1
    C1   name3     type1  10

感谢

Answer 1

来自separate包的tidyr可以帮助您。

   tidyr::separate(db, col = 3, into = c("type", "number"), sep = ":")

Answer 2

您可以在阅读了read.csv

之后拆分列

x = read.csv("myfile.txt", header = F, sep = ",")
y = matrix(unlist(strsplit(as.character(x$V3), ":")), ncol = 2, byrow = T)

x$V3 = y[, 3]
x$V4 = y[, 4]

  V1    V2    V3  V4
1 C1 name1 type1   2
2 C1 name2 type4   6
3 C2 name1 type2   1
4 C1 name3 type1  10
