scanFN {bayesSurv}

Read Data Values

Description

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

Usage

scanFN(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.
