r-在df文件字段上循环并存储为txt

Question

我有一个用户名如下的df

user                  pass
[e-mail]  123 
[e-mail]  456 
[e-mail]  789

我希望能够浏览列表并存储一个类似的txt文件

TXT File:
- user: [e-mail]
pass: 123
- user: [e-mail]
pass: 456
- user: [e-mail]
pass: 789

Thx！

Answer 1

我们可以paste列并使用cat写入文件

str1 <-  with(df1, paste('TXT File:n', 
paste('- user:', user, 'n', ' pass:', pass, collapse='n')))

cat(str1, 'file.txt')

打印到控制台

cat(str1, 'n')
TXT File:
- user: [e-mail] 
pass: 123
- user: [e-mail] 
pass: 456
- user: [e-mail] 
pass: 789 

数据

df1 <- structure(list(user = c("[e-mail]", "[e-mail]", 
"[e-mail]"), pass = c(123L, 456L, 789L)), class = "data.frame", row.names = c(NA, 
-3L))
