R: Reads the content of a local or an online text file

.readText {R.rsp} | R Documentation

## Reads the content of a local or an online text file

### Description

Reads the content of a local or an online text file.

### Usage

    .readText(con, ..., maxAge=getOption("R.rsp::downloadIfOlderThan", -Inf))

### Arguments

`con` | A `character` string specifying a local file or a URL, or a `connection`.
`...` | Not used.
`maxAge` | A `numeric` scalar specifying the maximum age (in seconds) of cached URL contents before downloading and recaching. If zero or less, the URL will always be downloaded.

### Value

Returns a `character` string.

### Caching URL

When reading online URLs, it may take time a significant time to read its content. If the content is changing rarely, it is possible to cache the content locally. If a cached version is found, then it is read instead. It is possible to control how often a file should be recached. If the cache is older than argument `maxAge` (in seconds), then the file is redownloaded and recached.

### Newline substitution

All occurances of `\r\n` and `\r` are replaced with `\n` such that all lines are ending in `\n` regardless of encoding.
