## Read Data Values

### Description

Read numeric data into a data frame from a file. Header is assumed to be present in the file.

### Usage

    scanFH(file, quiet=FALSE)

### Arguments

`file` | the name of a file to read data values from. If the specified file is `""`, then input is taken from the keyboard (or `stdin` if input is redirected). (In this case input can be terminated by a blank line or an EOF signal, `Ctrl-D` on Unix and `Ctrl-Z` on Windows.) Otherwise, the file name is interpreted relative to the current working directory (given by `getwd()`), unless it specifies an absolute path. Tilde-expansion is performed where supported. Alternatively, `file` can be a `connection`, which will be opened if necessary, and if so closed at the end of the function call. Whatever mode the connection is opened in, any of LF, CRLF or CR will be accepted as the EOL marker for a line and so will match `sep = "\n"`. `file` can also be a complete URL. To read a data file not in the current encoding (for example a Latin-1 file in a UTF-8 locale or conversely) use a `file` connection setting the `encoding` argument.
`quiet` | logical: if `FALSE` (default), scan() will print a line, saying how many items have been read.

### Details

See `scan`.

### Value

`data.frame` with read data values.
