Description Usage Arguments Value Author(s) See Also Examples
Generated colors in HSV units using either a one, two or three columns
matrix of values specified by argument x
. Each row in the matrix
corresponds to one color and each column to either H (hue),
S (saturation) or V (value). Which column that corresponds to which
channel can be controlled by the argument dim
. The intervals the
values in each column span can be specified by the argument
x.range
. Everything outside the range is safely thresholded. If
x.range
is NULL
, the range of each column in x
will
be used. The interval of each channel the input values should map into
can be specified by the argument dim.range
. By default this is
the full range of each channel, i.e. [0,1].

x |
A matrix of size Nx1, Nx2 or Nx3, where N is the number of data values. |
x.range |
A matrix of size 2x1, 2x2 or 2x3. |
dim |
A vector specifying what channel each columns controls. |
dim.range |
A matrix of size 2x1, 2x2 or 2x3. |

Not used. |
Returns a vector
of character
strings of length equal to the number of
rows (or the length) of x
. The resulting vector contains character
strings of format "#nnnnnn"
where n
is a hexadecimal digit.
