阅读2维阵列成R

Question

我的数据被存储在看起来像这样的文本文件：

1, { {0, 1}, {1, 0}, {2, 6} } 

2, { {0, 3}, {2, 2}, {0, 1} } 
... 

第一元件是一个整数，和第二个是一个2维阵列。有没有一个函数将它读入R？

Answer 1

data.frame(lapply(read.csv(text= 
"1, { {0, 1}, {1, 0}, {2, 6} } # will read the line as mostly character columns 
2, { {0, 3}, {2, 2}, {0, 1} } # with '{' and '}' just as non-syntactic characters 
", header=FALSE    ), 
    function(x) as.numeric(gsub("[^[:digit:]]", "", x)) 
      )  )

    V1 V2 V3 V4 V5 V6 V7 
1 1 0 1 1 0 2 6 
2 2 0 3 2 2 0 1
