本文介绍了当具有行名时，write.table将不需要的前导空列写入标头的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
检查此示例:
> a = matrix(1:9, nrow = 3, ncol = 3, dimnames = list(LETTERS[1:3], LETTERS[1:3]))
> a
A B C
A 1 4 7
B 2 5 8
C 3 6 9
该表正确显示.有两种不同的方式将其写入文件...
the table displays correctly. There are two different ways of writing it to file...
write.csv(a, 'a.csv')给出预期结果:
"","A","B","C"
"A",1,4,7
"B",2,5,8
"C",3,6,9
和write.table(a, 'a.txt')拧紧
"A" "B" "C"
"A" 1 4 7
"B" 2 5 8
"C" 3 6 9
的确，缺少一个空白的标签....这对于下游事物来说是一个痛苦.这是错误还是功能?有解决方法吗? (write.table(cbind(rownames(a), a), 'a.txt', row.names=FALSE除外)
indeed, an empty tab is missing.... which is a pain in the butt for downstream things.Is this a bug or a feature?Is there a workaround? (other than write.table(cbind(rownames(a), a), 'a.txt', row.names=FALSE)
干杯，扬尼克
推荐答案
引用?write.table， CSV文件部分:
所以你必须做
write.table(a, 'a.txt', col.names=NA)
你会得到
"" "A" "B" "C"
"A" 1 4 7
"B" 2 5 8
"C" 3 6 9
