盡管存在逗號，read.csv仍會跳過列

[英]read.csv skipping a column despite presence of a comma

原文 2017-11-02 14:37:02 2 2 r

str = "a,34° 49' 00\" S,58° 32' 00\" W,c,d"  
read.csv(textConnection(str), header = F)
#prints:
#V1                        V2 V3 V4
#1  a 34° 49' 00 S,58° 32' 00 W  c  d

列V2是"34° 49' 00 S,58° 32' 00 W" 。 當逗號將它分成兩列時，為什么read.csv將它組合成一列？

我應該改變什么才能返回：

V1              V2            V3 V4 V5
1  a 34° 49' 00 S  58° 32' 00 W  c   d

2 個解決方案

因為引用了逗號。 只需使用quote = NULL ：

read.csv(textConnection(str), header = F, quote = NULL)

該字符串中嵌入了引號，只需獲取read.csv即可忽略它們：

> read.csv(textConnection(str), header = F,quote="")
  V1            V2            V3 V4 V5
1  a 34° 49' 00" S 58° 32' 00" W  c  d

使用read.csv跳過r中的最后一列

[英]Skipping last column in r with read.csv

read.csv之后的列名以1開頭（原因是逗號結尾）

[英]Column names out by one after read.csv (cause is trailing comma)

用lapply跳過最后N行，然后讀取read.csv

[英]Skipping last N rows with lapply and then read.csv

read.csv 在 R 中跳過帶有前導空格的行

[英]read.csv is skipping lines with a leading whitespace in R

刪除 read.csv 中的索引列

[英]Remove index column in read.csv

如何讀取.csv 列作為邏輯而不是字符？
