我正在尝试读取一个包含24个列标题但另外包含14个空值的文件。请参见链接：https://www.elections.il.gov/ElectionInformation/CandDataFile.aspx?id=51
每当我运行下面的代码时，我都会收到消息
＆＃34;列数多于列名。＆＃34;
我觉得答案可能很简单。有什么想法吗？
candidates <- read.csv(file = "candidates.txt", sep = ",",
header = TRUE, stringsAsFactors = FALSE)
答案 0 :(得分：8)
一种解决方案是仅使用一个命令读取标题，一秒钟内没有标题的数据，然后删除多余的列并设置名称。
NAMES <- read.table("candidates.txt", nrow = 1, stringsAsFactors = FALSE, sep = ",")
DATA <- read.table("candidates.txt", skip = 1, stringsAsFactors = FALSE, sep = ",")
DATA <- DATA[, 1:24]
names(DATA) <- NAMES

在通过docker运行时，我遇到了类似的问题。因此，我必须先下载文件，然后再读取csv文件。

答案 2 :(得分：0)
我遇到了类似的问题，我认为问题出在标题上。因为当我删除标题（文件开头以“#”开头的行）时，不会发生错误。最后，下面链接中的解决方案解决了问题。它将参数 'skip' 设置为 1 以跳过文件的第一行（标题）。
