This is a convenience function to write the "source code" of inline R
expressions. For example, if you want to write `r 1+1` literally in an
R Markdown document, you may write `` `r knitr::inline_expr('1+1')`
``; for Rnw documents, this may be
\verb|\Sexpr{knitr::inline_expr{'1+1'}}|.
inline_expr(code, syntax)
Arguments
- code
Character string of the inline R source code.
- syntax
A character string to specify the syntax, e.g. rnw,
html, or md. If not specified, this will be guessed from
the knitting context.
Value
A character string marked up using the inline R code syntax.
Examples
library(knitr)
inline_expr("1+1", "rnw")
#> [1] "\\Sexpr{1+1}"
inline_expr("1+1", "html")
#> [1] "<!--rinline 1+1 -->"
inline_expr("1+1", "md")
#> [1] "`r 1+1`"
