dplyr - Ignore first four characters from tibble in R -


this question has answer here:

i have tibble want remove first 4 letters. unable it. tried substr() , substring() tend merge rows.

here's data:

dput(a) structure(list(value = c("abc-efgh-1234ijk-45k", "ijk-lokk-tiu" )), .names = "value", row.names = c(na, -2l), class = c("tbl_df",  "tbl", "data.frame"))

expected output:

"efgh-1234ijk-45k" "lokk-tiu"

here's tried:

try #1:

substr(as.data.frame.array(a),4,nchar(as.data.frame.array(a)))

but output is:

"t(`c(\"abc-efgh-ijk\", \"ijk-lokk-tiu\")` = 1:2)"

try#2:

stringr::str_sub((as.data.frame.array(a)),start = 4, end = nchar((as.data.frame.array(a))))

the output is:

"t(`c(\"abc-efgh-ijk\", \"ijk-lokk-tiu\")` = 1:2)"

i'd appreciate help.

this should work you

substr(a$value,5,nchar(a$value))
