我正在编写一个相当长的函数,它要求所有 colnames(abun) 都存在于 rownames(x) 中,反之则不然。如果不满足要求,我已经设计了它,以便函数抛出错误消息。除了错误消息,我还想告诉用户哪些 colnames(abun) 不在 rownames(x) 中。有任何想法吗?我当前的停止和错误消息如下所示:
abun <- matrix(c(0.4,0,0.6,0.1,0.4,0.5),
nrow = 2, ncol = 3, byrow = TRUE, dimnames = list(c("x", "y"),
c("A","B","E")))
abun
A B E
x 0.4 0.0 0.6
y 0.1 0.4 0.5
x<-data.frame("Trait1" =c(1,1,0,1),
"Trait2"=c(1,1,1,1),
"Trait3" =c(1,1,0,1),
"Trait4" =c(1,0,1,1))
rownames(x)<-c("A","B","C","D")
x
Trait1 Trait2 Trait3 Trait4
A 1 1 1 1
B 1 1 1 0
C 0 1 0 1
D 1 1 1 1
if(any(colnames(abun) %in% rownames(x) != TRUE))
stop("The following species names in abun are missing trait information")
