Sprintf doesn't care about OutDec option

[yurismol]

options(OutDec=",")
val = 0.86771
sprintf("%.3f", val)
#[1] "0.868"

Yes, this is mentioned in the documentation of help("options")...

OutDec: character string containing a single character. The preferred character to be used as the decimal point in output conversions, that is in printing, plotting, format and as.character but not when deparsing nor by sprintf nor formatC (which are sometimes used prior to printing.)

[gagolews]

Interestingly, https://linux.die.net/man/3/sprintf mentions that

For some numeric conversions a radix character ("decimal point") or thousands' grouping character is used. The actual character used depends on the LC_NUMERIC part of the locale. The POSIX locale uses '.' as radix character, and does not have a grouping character. Thus, printf("%'.2f", 1234567.89); results in "1234567.89" in the POSIX locale, in "1234567,89" in the nl_NL locale, and in "1.234.567,89" in the da_DK locale.

But this is not supported by base R

Stringi does not have it either - it is related to the (still missing) feature of formatting numerals (#81)

But this is reflected in a large number of other libraries.

It is definitely a feature worth having - added to the to-do list.
