Method for 'grobify' missing

[fpmassam]

I am running your sample code:

set.seed(1234)
d <- data.frame(x=rnorm(50), y=rnorm(50), 
                country=sample(c("ar","fr", "nz", "gb", "es", "ca"), 50, TRUE), 
                stringsAsFactors = FALSE)
ggplot(d, aes(x=x, y=y, country=country, size=x)) + 
  geom_flag() + 
  scale_country() +
  scale_size(range = c(0, 15))

but I get this error:

Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘grobify’ for signature ‘"NULL"’

Hi @fpmassam! Sorry about that. I won't be able to look into this until weekend, I'm afraid!

[fpmassam]

@Rensa Take your time :D

[jimjam-slam]

Hey @fpmassam, I'm having trouble reproducing this problem, but I notice in your sessionInfo() that ggflags is "loaded via a namespace (and not attached)" , rather than being an "other attached package" as it is in my setup.

Is it possible that you haven't loaded ggflags using library(ggflags) before running the sample code? I haven't modified since I forked this package, but it definitely ought to be there! 😅

[gustavo-jose]

Hey dear @fpmassam and @Rensa,

were you abe to find a solution for this error? I just happen to have stumble across it.
You can can find the code below together with my session info as well as the needed data attached.
For all regions I am able to build the nice figures with your beautiful flags but when I get to Europe, I get the same exact error as @fpmassam.
I would be extremely grateful for some advise :) Thanks!

CPI_2018.xlsx

# Europe 

CPI_2018_EUR <- dplyr::filter(.data = CPI_2018, region_name == 'Europe')

ggplot(data = CPI_2018_EUR, aes(x = reorder(ISO3, CPI_SCORE_2018),
                                y = CPI_SCORE_2018)) +
  geom_bar(stat = "identity") +
  coord_flip() +
  xlab("Country Code ISO3") +
  ylab("CPI Score 2018") +
  geom_flag(y = -1, aes(country = lower_case_iso_2), size = 4)

Hi @gustavo-jose! Thanks very much for the detailed info 😄

Are you able to post the column of European country codes in your data as plain text here? I just want to quickly check against this render of all the flags to see if there are any countries that might be missing from our database (because an invalid country code would trigger this error... I probably need to add some explicit checking in order to give more informative errors!).

[gustavo-jose]

Dear @Rensa,sorry for the unnecesary surplus information (pretty new into this) 🙈.
I have find the country triggering the error. For an unknown reason my dataset had an outdated iso2 for Serbia (cs instead of rs).
Sorry for bothering, as you wrote, I wasn't able to infer that this might be the issue out of the error text 😀 Thanks for the advise!

All the best for you,

Gustavo

[jimjam-slam]

That's okay! I'll open a new issue for improving the error text 😄
