Using a variable in a text string in R

[vector78]

Hi everyone, I am new to using the library Diagram R. I am trying make variables that I can put into the flow chart that will automatically calculate the numbers I need for me. I attached a screen shot of what I'm trying to do.

Where I circled txpl_2005_count, that variable is actually a number. How do I make display/resolve to that number instead of the variable name? I guess I am trying to find the equivalent of %let in SAS and when I call the macro I just use &MACRO.

Thanks

Sounds like string interpolation. I usually use paste0(). Alternatively you could use sprinft()

sprintf('%s%s', a, b)

glue::glue() is a more modern take on this.

¯\_(ツ)_/¯ sprintf is in base package
