I am trying to import a pdf file into R so I can work with the data.

text_ira <- pdf_text('./data/IRA-June2012-2020.pdf') %>% 
    str_split('\n') %>% 
    unlist()

ira <- data.frame(text = text_ira) %>% 
    filter(
        str_starts(text, '0') |
        str_starts(text, '1'))

when I type class(ira) it shows a data.frame.

But when I hit the command below (I only have 110 rows in the ira data frame):

ira <- ira[-c(1000),]

when I then type class(ira) it shows a character. Can someone please explain why that is?

I need it to show as a character in order to proceed. Thanks.

Can you provide a reproducible example? Either share the output of `text_ira` or make an example which you are able to share. – IceCreamToucan Oct 17 '21 at 19:41

The last command coerces to vector as `drop = TRUE`. you need `ira[-1000, , drop = FALSE]` – akrun Oct 17 '21 at 19:41

if you include `as_tibble()` somewhere you won't need `drop=FALSE` – Ben Bolker Oct 17 '21 at 20:03
Thanks, everyone for your quick response. I think the `drop = TRUE` makes sense. – max Oct 17 '21 at 20:08
