Data and Workspace Browser for Terminals 

========================================

[![](http://www.r-pkg.org/badges/version/dataview)](http://cran.rstudio.com/web/packages/dataview/index.html)

[![CRAN RStudio mirror downloads](http://cranlogs.r-pkg.org/badges/dataview)](http://cran.r-project.org/web/packages/dataview/index.html)

Terminal-based-tools for viewing data, summarizing contents of objects and environments, deciphering unknown objects, and aid debugging complex functions.

It was developed to facilitate working with R in combination with the brilliant text editor [vim](http://www.vim.org) or over ssh connections without RStudio server,

but it works fine within RStudio or other GUIs too.

Installation

------------

The latest official release of the package is available on CRAN.

```

install.packages("dataview")

```

You typically also want to add these lines to the end of your `~/.Rprofile` to auto-load the package and hide all objects created during the startup

```

require(dataview)

whos.exclude(ls())

```

and perhaps also

```

print.factor <- heat.view

```

Usage & Functionality

---------------------

`dataview` centers around the functions `whos` inspired by the same function in MATLAB,

`entry.view` inspired by data base systems,

and `heat.view` that can visualize long vectors in a very compact manner (especially factors).

More complex objects are however better studied with the `browse` function that combines the above functions in stepwise manner. Note that it also supports partial name matching and tab completion!

Colors

------

The color schemes used by `dataview` are defined in the `xtermStyle` package. To change the default palette (dark on light terminal background) you must attach it and do the following:

```

require(xtermStyle)

style.palette("light") # Designed for dark terminal background

```

`style.palette` also let's you define your own palette if you are not happy with the pre-defined ones.
