treeTotalBiomass(treecm)
treeTotalBiomass()所属R语言包:treecm
Returns the total biomass of the tree
返回的总生物量的树
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This is just a helper function, it sums the biomass of all logs and branches, as previously computed by treeBiomass
这仅仅是一个辅助函数,它总结了生物质所有log和分支机构的,如先前计算的treeBiomass,
用法----------Usage----------
treeTotalBiomass(treeData)
参数----------Arguments----------
参数:treeData
A named list that includes a fieldData data frame element, holding a biomass-named column. Note that the biomass column is added to the data frame by a previous call to treeBiomass function
命名的名单,其中包括一个fieldData数据框的元素,一个biomass命名的列。需要注意的是biomass列添加到数据框由以前的treeBiomass函数的调用
值----------Value----------
a real number or FALSE if the biomass column is NA
一个实数或FALSE如果biomass列NA
注意----------Note----------
This function may be used to compute the moment of the tree. Tree biomass (multiplied by standard gravity) is the tree force applied to its CM.
此功能可以用于计算时刻的树。林木生物量乘以标准重力是其CM树力。
