R help - Sep 2018 - argument "string" is missing, with no default

Hi All,

I am trying to fetch data from a pdf file with the below code but getting
the error message:
Error in stri_split_regex(string, pattern, n = n, simplify = simplify,  :
  argument "string" is missing, with no default

library(readr)library(stringr)library(magrittr)library(dplyr)
table_data <- nvsr65_05[ [ 14 ] ] %>%
  str_split(pattern = "\n") %>%
  unlist() %>%
  str_subset(pattern = "^[^?].*(\\. ){5}") %>%
  str_c(collapse = "\n") %>%
  read_table(col_names = FALSE) %>%
  mutate(X2 = str_replace_all(X2, "(\\. )*", ""),
	 X5 = rep(c("Neonatal", "Postnatal"), each = 10)) %>%
  set_names(value = c("rank", "cause_of_death",
"deaths", "percent", "group"))

Please advice. Thank you.

Use traceback() to see which function called stri_split_regex.

Break up the long pipeline into smaller parts so you can see where the 
error is comming from.

Don't post in HTML.
