我正在运行下面的代码来生成TraMineR序列对象列表。数据集可以在 [这里][1] 找到。

library(TraMineR)
sequences <- read.csv(file = "event-stream-20-l-m.csv", header = TRUE, nrows=10)
repo_names = colnames(sequences)

# 1. Loop across and define the 24 sequence objects & store them in sequence_objects
colpicks <- seq(10,240,by=10)
sequence_objects <- mapply(function(start,stop) seqdef(sequences[,start:stop]),
                           colpicks - 9, colpicks)

但是,如果我运行:

test <- sequence_objects[1]
seqdist(test, indel=1, with.missing=FALSE, norm="maxdist")

我收到的错误信息是:

Error:  [!] data is not a state sequence object, use 'seqdef' function to create one

怎么mapply使用seqdef不创建序列对象列表?

mapply默认情况下简化返回值。

根据上一个问题中的评论,尝试SIMPLIFY=FALSEmapply通话中加入。
