Does R have an equivalent of the Python f-string? Like this example in Python:
name = "Eric"
age = 42
f"Hello, {name}. You are {age}."
I know about paste and paste0, but they require you to separate the different elements with commas. I could not find anything about it while searching the Internet.

Python f-string is the newest Python syntax to do string formatting. It is available since Python 3.6. Python f-strings provide a faster, more readable, more concise, and less error prone way of formatting strings in Python. The f-strings have the f prefix and use {} brackets to evaluate values.
Also called “formatted string literals,” f-strings are string literals that have an f at the beginning and curly braces containing expressions that will be replaced with their values.
Answer. In Python, string formatters are essentially placeholders that let us pass in different values into some formatted string. The %d formatter is used to input decimal values, or whole numbers. If you provide a float value, it will convert it to a whole number, by truncating the values after the decimal point.
The r only disables backslash escape sequence processing, not f-string processing. Quoting the docs: The 'f' may be combined with 'r', but not with 'b' or 'u', therefore raw formatted strings are possible, but formatted bytes literals are not.
You can use glue:
library(glue)
name <- "Eric"
age <- 42
glue('Hello, {name}. You are {age}.')
#> Hello, Eric. You are 42.
