在 R 中提取公共连续序列的函数

Question

请问有没有从符号向量中提取出一个公共连续字符序列的函数。即例如从输入处的行向量：c ("mom soap frame", "sweet mom", "dad, mom, me", "`mom`ent")得到输出向量c("mom")

Answer 1

v <- c ("mom soap frame", "sweet mom", "dad, mom, me", "moment")

library(PTXQC)
LCSn(v, min_LCS_length = 0)

#[1] "mom"

function that extracts a common continuous sequence in R
