我对这个问题有点困惑: {{3}}。
我的模型的各个部分都有一个非常大的输出,它在tab2<-cbind (tab.info, tab1, summary)
str (tab2)
chr [1, 1:21] "EBF" "H2O" "517" "51" "8050" "1e-04" "0.7" "3" "poisson" "0.704811263414307" ...
- attr(*, "dimnames")=List of 2
..$ : NULL
..$ : chr [1:21] "V1" "V2" "n.obs" "n.sites" ...
上运行。输出汇总在一行中,并带有相关值。
model.results
我想将此行绑定到空矩阵model.results <- data.frame(Landclass= character(0), Resource = character(0), n.obs= integer(0), n.sites= integer(0), n.trees= integer(0),
learning.rate= numeric(0), bag.fraction= numeric(0),tree.complexityn.trees= integer(0),
family= character(0), mean.deviance= numeric(0), mean.residual.dev= numeric(0),
cv.correlation= numeric(0), correlation.mean= numeric(0), correlation.se= numeric(0),
alt= numeric(0),bio1= numeric(0), bio12= numeric(0), distance= numeric(0),
lat= numeric(0), lon= numeric(0), ndvi= numeric(0))
model.results<-rbind(tab2)
> model.results

,但每次执行此操作时,标题都会消失,并且不会添加新行。

有什么建议吗?
