mean: Arithmetric mean for objects generated by 'qntmap' package

In atusy/qntmap: Enhance quantitative analysis of EPMA map

Description

S3 methods for the arithmetric mean. See base::mean() for general use of mean().

Usage

## S3 method for class 'qntmap'
mean(x, index = "Whole area", cluster = NULL, density = NULL, ...)

## S3 method for class 'qm_xmap'
mean(x, index = "Whole area", cluster = NULL, density = NULL, ...)

## S3 method for class 'qm_cluster'
mean(x, index = "Whole area", cluster = NULL, density = NULL, ...)

Arguments

x	A qntmap class object returned by quantify() or qntmap().
index	A vector of length '1“ or length equal to number of pixels in map. An index can be created using mask image through segment().
cluster	A result of cluster_xmap() (i.e., qm_cluster class object). cluster is required when specifying density.
density	A named numeric vector specifying density of all the phases in x. (e.g., c(Qtz = 2.6, Ab = 2.6)).
...	Ignored

mean.qntmap

A returning value is a data.frame whose first column lists elements, and second to last columns lists mean values of each elements by index.
