关闭R中的options()调试模式

Question

在RI中可以通过激活调试模式options(error=recover).我怎么能把它关掉？我试着options()和options(NULL)和options(default=NULL),但他们都不把通过激活功能options(error=recover).

Answer 1

试试这个 :

options(error=NULL)

为了表明它的工作原理:

options(error=recover)
rnorm("k")
# Error in rnorm("k") : invalid arguments
# In addition: Warning message:
# In rnorm("k") : NAs introduced by coercion
# 
# Enter a frame number, or 0 to exit   
# 
# 1: rnorm("k")
# 
Selection: 0

options(error=NULL)
rnorm("k")
# Error in rnorm("k") : invalid arguments
# In addition: Warning message:
# In rnorm("k") : NAs introduced by coercion
