Interpolate expressions in a string
fmt(..., envir = parent.frame())chr(x)
html_escape(x)
interleave(a, b)
fmt(...) concatenates any unnamed arguments, and
interpolates all embedded expressions as explained in the ‘Details’.
Named arguments are treated as locally defined variables, and are added to
(and override, in case of name reuse) names defined in the calling scope.
chr(x) returns a string representation of a value or
unevaluated expression x.
html_escape(x) returns the HTML-escaped version of x.
interleave(a, b) returns a vector c(a[1], b[1], a[2],
b[2], ..., a[n - 1], b[n - 1], a[n]).
one or more unnamed character string arguments, followed optionally by named arguments
an object to convert
a character vector of length n
a character vector of length n - 1
fmt interpolates embedded expressions in a string.
chr converts a value to a character vector; unlike
as.character, it correctly deparses unevaluated names and expressions.
interleave is a helper that interleaves two vectors a = c(a[1],
..., a[n]) and b = c(b[1], ..., b[n - 1]).
The general format of an interpolation expression inside a fmt string
is: {...} interpolates the expression .... To insert
literal braces, double them (i.e. {{, }}). Interpolated
expressions can optionally be followed by a format modifier: if
present, it is specified via the syntax {...;modifier}. The
following modifiers are supported:
\"like dQuote(...)
\'like sQuote(...)
‹fmt›flike sprintf('%‹fmt›f', ...)
Vectors of length > 1 will be concatenated as if using
toString before interpolation.
