Calculates aggregated statistics of GLRLM matrix statistics calculated on GLRLM matrices evaluated in all different directions.
1 2  glrlm_stat_all(RIA_data_in, statistic = "mean(X, na.rm = TRUE)",
verbose_in = TRUE)

RIA_data_in 
RIA_image. 
statistic 
string, defining the statistic to be calculated on the array of GLRLM statistics. By default, statistic is set to "mean", however any function may be provided. The proper syntax is: function(X, attributes). The supplied string must contain a "X", which will be replaced with the array of the GLRLM statistics value. Further attributes of the function may also be given. For example, if you wish to calculate the median of all GLRLMs calculated in different directions, then it must be supplied as: median(X, na.rm = TRUE). 
verbose_in 
logical, indicating whether to print detailed information.
Most prints can also be suppressed using the 
RIA_image containing the statistical information.
