operator_dollar: as a Binary Operator¶
Description¶
Provides access to stri_sprintf in form of a binary operator in a way similar to Python’s % overloaded for strings.
Missing values and empty vectors are propagated as usual.
Usage¶
e1 %s$% e2
e1 %stri$% e2
Arguments¶
|
format strings, see |
|
a list of atomic vectors to be passed to |
Details¶
Vectorized over e1 and e2.
e1 %s$% atomic_vector is equivalent to e1 %s$% list(atomic_vector).
Value¶
Returns a character vector.

Other length: stri_isempty(), stri_length(), stri_numbytes(), stri_pad_both(), stri_sprintf(), stri_width()
Examples¶
"value='%d'" %s$% 3
## [1] "value='3'"
"value='%d'" %s$% 1:3
## [1] "value='1'" "value='2'" "value='3'"
"%s='%d'" %s$% list("value", 3)
## [1] "value='3'"
"%s='%d'" %s$% list("value", 1:3)
## [1] "value='1'" "value='2'" "value='3'"
"%s='%d'" %s$% list(c("a", "b", "c"), 1)
## [1] "a='1'" "b='1'" "c='1'"
"%s='%d'" %s$% list(c("a", "b", "c"), 1:3)
## [1] "a='1'" "b='2'" "c='3'"
