RMarkdown with underscores variables

aibl_apoeres <- read_csv('aibl_apoeres_01-Jun-2018.csv')
aibl_cdr_01 <- read_csv('aibl_cdr_01-Jun-2018.csv') %>%
                  dplyr::filter(VISCODE=='bl')
aibl_labdata <- read_csv('aibl_labdata_01-Jun-2018.csv') %>%
                  dplyr::filter(VISCODE=='bl')

How to I make the underscore displayed properly?
Thanks.

We need sample dasa anu a reprex

Unfortunately, in RMarkdown an underscore is a special character in certain circumstances. If you precede it with a backslash you'll get the underscore. Write aibl\_apoeres.

But in most places the underscore should be fine, so a reprex will help.
