R: Parse, retaining comments.

parse_all {evaluate} | R Documentation

## Parse, retaining comments.

### Description

Works very similarly to parse, but also keeps original formatting and comments.

### Usage

    parse_all(x, filename = NULL, allow_error = FALSE)

### Arguments

`x` | object to parse. Can be a string, a file connection, or a function
`filename` | string overriding the file name
`allow_error` | whether to allow syntax errors in `x`

### Value

A data.frame with columns `src`, the source code, and `expr`. If there are syntax errors in `x` and `allow_error = TRUE`, the data frame has an attribute `PARSE_ERROR` that stores the error object.
