一、背景介绍随着循证医学(evidence-based medicine)的兴起,森林图(forest plot)已经为人所广泛认识。当前,几乎所有临床工作者都知道什么是森林图,以及如何解读森林图的含义。 Richard Peto曾以玩笑的口吻…
Choosing to call the function will require you to build the table LABEL and to control the ordering of the variables. The forest_plot help has several examples. The package also include vignettes with several step-by-step detailed examples: PK example Pediatric example PK PD example Exposure ...
We used a linear mixed-effects (LME) model of understory PAI, upper canopy PAI and a combination of both strata (total PAI) measured from TLS in each transect as a function of time of measurement (time). We also included an interaction term with the plot category of location near an edg...
urease activity in this plot even exceededthe activity measured in the undisturbed soil. This activity also increased remarkably in the plots treated with NPK plus a fertile soil layer and with NPK plus coal (6+60tha−1), but it did not reach the level of urease activity in the undisturbe...
(ii) local-scale gradients in resource availability affect the composition of plant species due to differences in their life-history strategy; and thus (iii) plot-scale vegetation C stocks differ in association with the locally dominant plant functional group (trees, palms, lianas) due to ...

示例数据“otu_table.txt”中,共记录了45个连续生长时间中植物根际土壤样本中细菌OTU的相对丰度信息。 “plant_age.txt”中,记录了这45个根际土壤样本对应的植物生长时间,时间单位是天。 随机森林回归模型的初步构建 将OTU丰度数据读入R中,可以事先作一些预处理,例如剔除低丰度类群等。 随后,对应OTU丰度样本与植物...
The plot numbers and treatments (see Table 2) used in the present study are shown. The grouping in blocks is based on similarities in tree basal area and plot vicinity. Full size image The Hasslöv site is a former Calluna vulgaris (L.) Hull heathland with scattered Vaccinium myrtillus ...
Scree plot is generated to prioritize the number of significant principal components (Jackson1993). Finally, a series of ordinations were created to interpret the PCs visually and determine their fragmentation patterns. The sum of the eigenvalues is equal to the variance of the original data set,...
