我试图在我的数据集（下面发布的代码和数据集示例）上使用Codyn包和函数multivariate_change（）。我需要解决多条记录错误。
library(codyn)
multivariate_change(df,
time.var="time",
replicate.var = "replicate",
species.var = "species",
abundance.var = "abundance")
Error in check_single(df, species.var, time.var = time.var, replicate.var = replicate.var) :
Multiple records for one or more species found at:
time replicate
"2.2017" "111"
"2.2013" "135"
"2.2014" "135" etc.etc.
