Problem with options(readr.show_col_types = FALSE)

[lukeholman]

Hi there,

The option options(readr.show_col_types = FALSE) does not currently work for me, as shown below. When I pass show_col_types = FALSE directly to read_csv(), it works fine. Session info below.

Thank you for opening the issue with a reproducible example!

This is happening because the option is actually called readr.show_types in the code 🙈

readr/R/utils.R

Line 35 in 3c46de1

if (identical(getOption("readr.show_types", TRUE), FALSE)) {

I now think it makes more sense to name option this the same as the argument name, and that is what is in the documentation elsewhere, so this is now fixed to work how you were expecting.

library(readr)
options(readr.show_col_types = FALSE)
read_csv(readr_example("mtcars.csv"))

Hi thank you for this hint and the wonderful package. Actually, it doesn't work for me now if I use
options(readr.show_types = FALSE). Only if I use options(readr.show_col_types = FALSE) it worked for me now.
I am using it in an R notebook, readr Version 2.1.2. R.version 4.2.1 The autocomplete function of R Studio 2022.7.1.554 only suggests the readr.show_types option.

```{r}
library(readr)
options(readr.show_types = FALSE)

read_csv(readr_example("mtcars.csv"))

Best wishes,

I can confirm that for me too options(readr.show_col_types = FALSE) and show_cols does not. Latest CRAN version 2.1.2
