Adding "Breaks" in "htmlescape" - html

Question

I am following this tutorial here (https://rstudio.github.io/leaflet/popups.html):
library(htmltools)
library(leaflet)
df <- read.csv(textConnection(
"Name,Lat,Long
Samurai Noodle,47.597131,-122.327298
Kukai Ramen,47.6154,-122.327157
Tsukushinbo,47.59987,-122.326726"
))
leaflet(df) %>% addTiles() %>%
addMarkers(~Long, ~Lat, popup = ~htmlEscape(Name))
Now, I want to the popups to display the information about the name, the longitude and the latitude (i.e. title + value) - I would like it to say:
Name = Insert Restaurant Name Here
(new line)
Longitude = Insert Longitude Name Here
(new line)
Latitude = Insert Latitude Here
I thought that this could be done as follows:
leaflet(df) %>% addTiles() %>%
addMarkers(~Long, ~Lat, popup = ~htmlEscape(df$Name, df$Lat, df$Long))
But this is giving me the following error:
Error in htmlEscape(df$Name, df$Lat, df$Long) : unused argument (df$Long)
I tried to read about this function (https://www.rdocumentation.org/packages/htmltools/versions/0.5.2/topics/htmlEscape), but there does not seem to be too much information on how to use it. I thought that maybe this might require "combining" all the arguments together:
leaflet(df) %>% addTiles() %>%
addMarkers(~Long, ~Lat, popup = ~htmlEscape(c(df$Name, df$Lat, df$Long)))
But now this only displays the final argument (and that too, without the title).
Is "htmlescape()" able to handle multiple arguments?
Thank you!
