Supplementary Table 2 from Rapid diversification of vascular architecture underlies the Carboniferous fern radiation

Table S2: The loadings that best describe each of the 5 clusters of vascular architecture. MeanIn Category, sd in category describes the mean and standard deviation of the loading value for the specific vascular architecture. Overall mean and Overall sd describes the mean and standard deviation of the loading for all individuals in the analysis. The p.value denotes whether the mean loading for the specific vascular architecture is significantly different from the overall mean.

表S2：最能表征5组血管架构聚类特征的载荷值。其中，「分类内均值（MeanIn Category）」与「分类内标准差（sd in category）」分别指代对应特定血管架构的载荷值的均值与标准差；「总体均值（Overall mean）」与「总体标准差（Overall sd）」指代本次分析中全部个体的载荷值均值与标准差；「p值（p.value）」用于判断特定血管架构的平均载荷值与总体平均载荷值是否存在显著差异。
