plt.2dcm | R Documentation |
This function creates a ggplot visualization from a 2D correlation matrix,
such as those produced by cm.sr
or cm.nsr
. The function attempts
to extract numeric wavelengths from the column names. If the extraction fails,
sequential indices are used.

A numeric 2D matrix of correlation coefficients. |

Optional ggplot2 aesthetic mapping. |

Logical. If |
environment |
The environment in which to evaluate the plot. Defaults to |
It replaces the former ggplot.cm()
.
The function extracts numeric wavelengths from the column names of data
.
If these cannot be determined, sequential indices are used instead.
A ggplot object visualizing the correlation matrix.
