Importing columns from .csv as a "character" type instead of integer in R

I'm trying to import a single column from a .csv file as a character in the same way that id <- c("341432", "52312", "63432") would do. However, when I do the following:

id <- idfromcsv[[1]]

R imports this as an integer when I try typeof(id). How do I import a single column from a .csv in the exact same way that id <- c("341432", "52312", "63432") would do it?

this is similar to https://stackoverflow.com/questions/5788117/only-read-selected-columns – Hunaidkhan May 26 '20 at 03:03
Use `readr::read_csv.` It has a `col_types` argument that allows you to specify _character_. Read `vignette("readr")` for details. – David T May 26 '20 at 04:19
What is `idfromcsv` ? – Ronak Shah May 26 '20 at 08:33
@RonakShah `idfromcsv <- read.csv("patientidlist.csv")`, i.e. it's a `read.csv()` of the list of patient ID's of interest – psa May 27 '20 at 00:57
