RDA - fractional size

Redundancy Analysis of the effect of depth on the fractional size (length/maximum length) of species in stations. Depth of stations is also required as an input and can be found in 'Values per station'. Species names can be found in 'Species codes'. See link for fileset description.针对采样站位内物种相对体长（体长/最大体长）受水深影响的冗余分析（Redundancy Analysis）。站位水深为所需输入变量之一，可从「各站位参数值（Values per station）」中获取；物种名称可从「物种编码表（Species codes）」中查询。有关文件集的详细说明，请参阅相关链接。
