| \title{Invoke a Data Viewer} |
| \description{ |
| Invoke a spreadsheet-style data viewer on a matrix-like \R object. |
| } |
| \usage{ |
| View(x, title) |
| } |
| \arguments{ |
| \item{x}{an \R object which can be coerced to a data frame with |
| non-zero numbers of rows and columns.} |
| \item{title}{title for viewer window. Defaults to name of \code{x} |
| prefixed by \code{Data:}.} |
| } |
| \details{ |
| |
| Object \code{x} is coerced (if possible) to a data frame, then |
| columns are converted to character using \code{\link{format.data.frame}}. |
| The object is then viewed in a spreadsheet-like data viewer, a |
| read-only version of \code{\link{data.entry}}. |
| |
| If there are row names on the data frame that are not \code{1:nrow}, |
| they are displayed in a separate first column called \code{row.names}. |
| |
| Objects with zero columns or zero rows are not accepted. |
| |
| \describe{ |
| \item{On Unix-alikes,}{the array of cells can be navigated by the |
| cursor keys and Home, End, Page Up and Page Down (where supported by |
| X11) as well as Enter and Tab.} |
| \item{On Windows,}{the array of cells can be navigated \emph{via} |
| the scrollbars and by the cursor keys, Home, End, Page Up and Page Down. |
| |
| On Windows, the initial size of the data viewer window is taken |
| from the default dimensions of a pager (see \code{\link{Rconsole}}), |
| but adjusted downwards to show a whole number of rows and columns.} |
| } |
| } |
| \value{ |
| Invisible \code{NULL}. The functions puts up a window and returns |
| immediately: the window can be closed via its controls or menus. |
