| spiderByGroupPatterns {GCDkit} | R Documentation | 
Plots a series of spiderplots, for each group one, in which individual patterns are shown.
spiderByGroupPatterns(rock = WR, norm = NULL, bw = FALSE,
    ymin = 0, ymax = 0, xrotate = FALSE, offset = TRUE, centered = FALSE)
| rock | a numeric matrix; the whole-rock data from which will be filtered out those to be normalized. | 
| norm | a character string specifying the model. | 
| bw | logical; should be the plot black and white? | 
| ymin, ymax | y range of the diagram. | 
| xrotate | logical; shall be the element names on x axis rotated? | 
| offset | logical; shall be the names for odd and even elements shifted relative to each other? | 
| centered | logical; shall be the element names on x axis plotted in between tick marks? | 
Firstly, the normalization scheme is chosen and scaling for all the plots specified. Then, a series of spiderplots is plotted, for each group one, in which patterns for individual samples are shown.
Returns a list 'results' with the normalized values, and, in case of REE, some extra parameters.

For the syntax of the setup file with normalizing values and adding new 
normalization schemes see selectNorm. This function is based on 
spider.
