RgbToCol

RgbToLong

LongToRgb

the color in rgb code, say a matrix with the red, green and blue code in the rows.  

character string specifying the color space to be used. Can be <code>"rgb"</code> (default) or <code>"hsv"</code>.

method

character string specifying the metric to be used for calculating distances between the colors.
        Available options are <code>"euclidean"</code> (default) and <code>"manhattan"</code>. Euclidean distances are root sum-of-squares of
        differences, and manhattan distances are the sum of absolute differences.

metric

Convert a RGB-color to a named R-Color means looking for a color in the R-palette, which is nearest to the given RGB-color.
The function uses the minimum of squared distance as proximity measure. 
RgbToLong converts an RGB-color to a long integer in numeric format.<p></p><p></p>

 color 

A collection of miscellaneous basic statistic functions and convenience wrappers for efficiently describing data. The author's intention was to create a toolbox, which facilitates the (notoriously time consuming) first descriptive tasks in data analysis, consisting of calculating descriptive statistics, drawing graphical summaries and reporting the results. The package contains furthermore functions to produce documents using MS Word (or PowerPoint) and functions to import data from Excel. Many of the included functions can be found scattered in other packages and other sources written partly by Titans of R. The reason for collecting them here, was primarily to have them consolidated in ONE instead of dozens of packages (which themselves might depend on other packages which are not needed at all), and to provide a common and consistent interface as far as function and arguments naming, NA handling, recycling rules etc. are concerned. Google style guides were used as naming rules (in absence of convincing alternatives). The 'camel style' was consequently applied to functions borrowed from contributed R packages as well.
