Evaluate R code by chunks, then insert the output to each chunk. As the output is masked in comments, the source code will not break.
tidy_eval(
source = "clipboard",
...,
file = "",
prefix = "## ",
envir = parent.frame()
)Evaluated R code with corresponding output (printed on screen or written to a file).
The input file name (by default the clipboard; see
tidy_source()).
Other arguments passed to tidy_source().
The file name to write to via cat().
The prefix to mask the output.
The environment in which to evaluate the code. By default the
parent frame; set envir = NULL or envir = new.env() to avoid
the possibility of contaminating the parent frame.
library(formatR)
## evaluate simple code as a character vector
tidy_eval(text = c("a<-1+1;a", "matrix(rnorm(10),5)"))
## evaluate a file
tidy_eval(system.file("format", "messy.R", package = "formatR"))
