[R] Please help with ggplot error

Wed Jun 12 21:01:10 CEST 2019

Hello,

This seems to be a conflict with a generic function margin() from 
another package you might have loaded. ggplot::margin is not generic, 
therefore there are no methods for it. And its arguments have default 
values, it wouldn't throw an error even when called with no arguments. 
(As it is in theme_tq).

The code I have loaded is

getAnywhere('margin')
A single object matching ‘margin’ was found
It was found in the following places
   package:ggplot2
   namespace:ggplot2
with value

function (t = 0, r = 0, b = 0, l = 0, unit = "pt")
{
     u <- unit(c(t, r, b, l), unit)
     class(u) <- c("margin", class(u))
     u
}
<bytecode: 0x78cc180>
<environment: namespace:ggplot2>

This is called 3 times in theme_tq and none of them causes problems.

Hope this helps,

Rui Barradas
