insertChunk: Insert a code chunk into an R Markdown file
In elastacloud/automatic-data-explorer: Automatic Data Exploration

Description Usage Arguments Value Examples

This function can be used to insert any line or lines of code into an R Markdown file. The chunk will be inserted into the file called filename.Rmd, which must exist in the current working directory. Chaining with %>% is possible, by returning filename from the function.

1	insertChunk(filename, object, chunktitle = NULL)

`filename`	Character giving the name of the R Markdown file that the chunk should be inserted into, minus the `.Rmd` extension
`object`	Can be any quoted or unquoted line of R code, i.e. a call to a function to insert a single line. To insert more than one line, pass as a vector of type `"expression"`.
`chunktitle`	Single or vector of character/s giving an optional markdown header that will be included before the code chunk e.g. of the form `"# Header", "## Header", "### Header"`. Pass as a vector of titles of equal length to object expressions if multiple headers required.

Returns filename so that functions can be chained to write to the same file consecutively

## Not run: 

## Insert single chunk, chained from createFile() function

createFile("Mtcars") %>% insertYAML(title = "Test", author = "J. Bloggs") %>%
                         insertLibraries() %>%
                         insertChunk(summary(mtcars), title = "#Summary")

                         insertChunk("summary(mtcars)", title = "#Summary") would also work

## Insert multiple chunks to existing file, with headers

insertChunk("Mtcars.Rmd",
                 expression(
                      plot(mtcars$cyl, mtcars$hp),
                      multivariateCorrelation(mtcars)),
                            title= c("##Scatter Plot",
                                     "##Correlations"))
