V10列是一个大列，由24个V和N分隔。 V是“有效”的观测值，N是无效的观测值。
我想分隔V10列。我尝试使用以下方法，但不能解决N问题。
sep_data <- df %>%
separate(V10, into = paste("x",1:24, sep = "_"), sep = "V")
看tail()中的sep_data：

答案 0 :(得分：1)
如何基于V或N使用split（）进行分离？ sep = "V|N"。
但是我建议进行预处理。使用gsub或stringr::str_replace_all使N项NA 之前分开。类似于df$V10 = gsub("N\\d+(\\.)?\\d+", "VNA", df$V10)。将NXXX.XX替换为VNA，然后在V上进行分割，应使NA保留原来的N所在的位置。
