我不认为这将成为可能,在整个R. ?options
显示效果一般说,这大概数字:
‘digits’: controls the number of digits to print when printing
numeric values. It is a suggestion only. Valid values are
1...22 with default 7. See the note in ‘print.default’ about
values greater than 15.
关键的一句是“这只是一个建议。”
接下来,请注意,所打印的内容首先受应用的print()
方法的管理(这在交互式使用期间被隐藏,因为R auto-print()
s)。有关详细信息,请参阅?print
和?print.default
以了解基本方法。从?print.default
我们注意到
digits: a non-null value for ‘digits’ specifies the minimum number of
significant digits to be printed in values. The default,
‘NULL’, uses ‘getOption(digits)’. (For the interpretation
for complex numbers see ‘signif’.) Non-integer values will
be rounded down, and only values greater than or equal to 1
and no greater than 22 are accepted.
,并在详细部分,我们有:
The same number of decimal places is used throughout a vector.
This means that ‘digits’ specifies the minimum number of
significant digits to be used, and that at least one entry will be
encoded with that minimum number. However, if all the encoded
elements then have trailing zeroes, the number of decimal places
is reduced until at least one element has a non-zero final digit.
Decimal points are only included if at least one decimal place is
selected.
为digits
默认为NULL
表明getOption("digits")
被使用,但正如我们已经指出的那样,这是一个仅指导。
似乎没有办法配置R做你想做的事情,也不是全局做。您需要重写print.default()
或您需要使用的所有print()
方法,并使用这些版本代替标准版本---现在不适用于NAMESPACES。
你能给出预期的输出吗?你的意思是把'lun'的coef打印为'0.000000'? –
是的,除非明确指定其他精度,我想有0.000000。 –
