clipboard_import(sep = "\\t", quote = "", header = TRUE, dec = ".",

|
|
\arguments{
|
|
\item{sep}{the field separator character. Values on each line of the
|
|
file are separated by this character. If \code{sep = ""} (the
|
|
default for \code{read.table}) the separator is \sQuote{white space},
|
|
that is one or more spaces, tabs, newlines or carriage returns.}
|
|
|
|
\item{quote}{the set of quoting characters. To disable quoting
|
|
altogether, use \code{quote = ""}. See \code{\link{scan}} for the
|
|
behaviour on quotes embedded in quotes. Quoting is only considered
|
|
for columns read as character, which is all of them unless
|
|
\code{colClasses} is specified.}
|
|
|
|
\item{header}{a logical value indicating whether the file contains the
|
|
names of the variables as its first line. If missing, the value is
|
|
determined from the file format: \code{header} is set to \code{TRUE}
|
|
if and only if the first row contains one fewer field than the
|
|
number of columns.}
|
|
|
|
\item{dec}{the character used in the file for decimal points.}
|
|
|
|
\item{na}{the string to use for missing values in the data.}
|
|
|
|
\item{stringsAsFactors}{logical: should character vectors be converted
|
|
to factors? The \sQuote{factory-fresh} default is \code{TRUE}, but
|
|
this can be changed by setting \code{\link{options}(stringsAsFactors
|
|
= FALSE)}.}
|
|
|
|
\item{startrow}{\emph{n}th row to start importing from. When \code{header = TRUE}, the import will start on row \code{startrow} \emph{below} the header.}
|
|
|
|
\item{as_vector}{a logical value indicating whether data consisting of only one column should be imported as vector using \code{\link[dplyr]{pull}}. This will strip off the header.}
|
|
|
|
\item{guess_col_types}{a logical value indicating whether column types should be guessed and transformed automatically with \code{\link[readr]{parse_guess}} from the \code{readr} package. Besides, the antimicrobial classes in this AMR package (\code{\link{as.rsi}} and \code{\link{as.mic}}) are also supported.}
|
|
|
|
\item{date_names}{Character representations of day and month names. Either
|
|
the language code as string (passed on to \code{\link[=date_names_lang]{date_names_lang()}})
|
|
or an object created by \code{\link[=date_names]{date_names()}}.}
|
|
|
|
\item{date_format}{Default date and time formats.}
|
|
|
|
\item{time_format}{Default date and time formats.}
|
|
|
|
\item{remove_ASCII_escape_char}{remove ASCII escape character}
|
|
|
|
\item{tz}{Default tz. This is used both for input (if the time zone isn't
|
|
present in individual strings), and for output (to control the default
|
|
display). The default is to use "UTC", a time zone that does not use
|
|
daylight savings time (DST) and hence is typically most useful for data.
|
|
The absence of time zones makes it approximately 50x faster to generate
|
|
UTC times than any other time zone.
|
|
|
|
Use \code{""} to use the system default time zone, but beware that this
|
|
will not be reproducible across systems.
|
|
|
|
For a complete list of possible time zones, see \code{\link{OlsonNames}()}.
|
|
Americans, note that "EST" is a Canadian time zone that does not have
|
|
DST. It is \emph{not} Eastern Standard Time. It's better to use
|
|
"US/Eastern", "US/Central" etc.}
|
|
|
|
\item{encoding}{encoding to be assumed for input strings. It is
|
|
used to mark character strings as known to be in
|
|
Latin-1 or UTF-8 (see \code{\link{Encoding}}): it is not used to
|
|
re-encode the input, but allows \R to handle encoded strings in
|
|
their native encoding (if one of those two). See \sQuote{Value}
|
|
and \sQuote{Note}.
|
|
}
|
|
|
|
\item{info}{print info to console}
|
|
|
|
\item{x}{the object to be written, preferably a matrix or data frame.
|
|
If not, it is attempted to coerce \code{x} to a data frame.}
|
|
}
|
|
\description{
|
|
These are helper functions around \code{\link{read.table}} and \code{\link{write.table}} to import from and export to clipboard with support for Windows, Linux and macOS.
|
|
|
|
The data will be read and written as tab-separated by default, which makes it possible to copy and paste from other software like Excel and SPSS without further transformation.
|
|
|
|
This also supports automatic column type transformation, with AMR classes \code{\link{as.rsi}} and \code{\link{as.mic}}.
|
|
}
|
|
\details{
|
|
The parameter \code{stringsAsFactors} defaults to \code{FALSE}, as opposed to most base \R methods.
|
|
|
|
The parameters \code{date_format} and \code{time_format} also support generic date and time formats like \code{"dd-mm-yyyy"} like Excel.
