我不認爲這將成爲可能,在整個R. ?options
顯示效果一般說,這大概數字:
‘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.
關鍵的一句是「這只是一個建議。」
接下來,請注意,所打印的內容首先受應用的print()
方法的管理(這在交互式使用期間被隱藏,因爲R auto-print()
s)。有關詳細信息,請參閱?print
和?print.default
以瞭解基本方法。從?print.default
我們注意到
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.
,並在詳細部分,我們有:
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.
爲digits
默認爲NULL
表明getOption("digits")
被使用,但正如我們已經指出的那樣,這是一個僅指導。
似乎沒有辦法配置R做你想做的事情,也不是全局做。您需要重寫print.default()
或您需要使用的所有print()
方法,並使用這些版本代替標準版本---現在不適用於NAMESPACES。
你能給出預期的輸出嗎?你的意思是把'lun'的coef打印爲'0.000000'? –
是的,除非明確指定其他精度,我想有0.000000。 –
