我正在运行下面的代码来生成一个序列对象列表TraMineR
。数据集可以在[这里]找到[1]。使用mapply在R/TraMineR中创建序列对象?
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")
我收到的错误消息是:
Error: [!] data is not a state sequence object, use 'seqdef' function to create one
这怎么可能,使用seqdef
的mapply
不不创建一个列表序列对象?
