与 python pip 不同，R 似乎公开了为.Rprofile. 我想这是因为 R 将字符串视为 URL。

local({r <- getOption("repos")
       r["Nexus"] <- "https://username:password@my-private-r-repo.com/repository/r-group"
       options(repos=r)
})

然后当我安装包时：

> install.packages("shinydashboard")
trying URL 'https://username:password@my-private-r-repo.com/repository/r-group/bin/macosx/el-capitan/contrib/3.6/shinydashboard_0.7.1.tgz'
Content type 'application/x-tgz' length 326031 bytes (318 KB)
==================================================
downloaded 318 KB


The downloaded binary packages are in
    /var/folders/7_/pt_pgg2j531f2jc_n5znht600000gn/T//RtmpZkpXkN/downloaded_packages

R 是否有配置选项来防止凭据泄露？

我有一个数据库表，我想返回其中列在字符串中任意位置包含非 ASCII 字符的所有值。

是否有捷径可寻？

我试过这个

select col_name,  regexp_instr(col_name,'[^[:ascii:]]') 
from test_table s
where created > sysdate - 1 
and regexp_instr(col_name,'[^[:ascii:]]') > 0 
limit 5;

但出现此错误：

error:  Invalid character class name, collating name, or character range.  The error occured while parsing the regular expression: '[^[:>>>HERE>>>ascii:]]'.
  code:      8002
  context:   T_regexp_init
  query:     5059536
  location:  funcs_expr.cpp:130
  process:   query20_31 [pid=7903]

谢谢！
