rstringsplitgrep

Regex pattern to include string while excuding other patterns

I have a long table including such texts in each line "

Each level was separated by "|".

I want to split them based on different levels in R, such as

Subset 1

Subset 2

Subset 3

Subset 4

Thanks in advance

Solution

  • Sounds like you want to count the number of "|" characters and split accordingly.

    split(your_vector, stringr::str_count(your_vector, pattern = fixed("|")))
# $`0`
# [1] "x__lorem_01" "x__lorem.05"
# 
# $`1`
# [1] "x__lorem|y__ipsum"       "x__lorem|y__ipsum004_01"
# 
# $`2`
# [1] "x__lorem.05|y__ipsum|z__dolor02_sit"
# 
# $`3`
# [1] "x__lorem.05|y__ipsum|z__dolor02_sit|t__consectetur.adipiscing02"

    Using this sample data

    your_vector = c(
    "x__lorem_01",
    "x__lorem|y__ipsum",
    "x__lorem.05",
    "x__lorem.05|y__ipsum|z__dolor02_sit",
    "x__lorem.05|y__ipsum|z__dolor02_sit|t__consectetur.adipiscing02",
    "x__lorem|y__ipsum004_01" 
)
