gganimate won't render when combining geom_point and geom_sf
0
I'm trying to animate points moving over a map in gganimate. In teh following example, animating just the points works and a static plot of the points and map works, but combining them fails with the error Error in mapply(FUN = f, ..., SIMPLIFY = FALSE) : zero-length inputs cannot be mixed with those of non-zero length
Here's a repro:

gganimate is not on cran, otherwise a great MWE. Could you add a comment with the devtools::install code? Just as speculation, where do the arguments to transitions_components come from? It seems you would need an sf object with a time series of centering points.

gganimate is not on cran, otherwise a great MWE. Could you add a comment with the devtools::install code? Just as speculation, where do the arguments to transitions_components come from? It seems you would need an sf object with a time series of centering points.

I'm not sure what you mean.trackidis defined ind. It's 1 for the first 100 rows and 2 for the second 100 rows. It's undefined inarea, but then again so istime.

Added an answer, b/c that's the only way I've found to do code blocks. When running the example time ends up in the namespace because it's globally defined, but trackid doesn't; it's local to the d, track1 and track2 objects. You do call d in the initial ggplot() for p2, but then for geom_sf, you use area as the data. d is a tibble and if you want to refer to it's components, you either have to do it explicitly, as in d$trackid or through %>% when you can use the bare name.

I don't think that's correct.transition_componentstakes unquoted column names just likeaesinggplot. Also, if it was a matter oftrackidbeing undefined then the first animated plot wouldn't work, but this does: p <- ggplot(d, aes(lon, lat)) + geom_point() + labs(subtitle = 'Date: format(frame_time, "%b %e")') + transition_components(trackid, time) + shadow_trail(distance = 0.01, size = 0.3) animate(p, 100, 20)

d in the first animation works because it sets the data and the + arguments don't change it, so there's no need to quote "tracked." "Time" is already global.

transition_components()totransition_time() - Changed
shadow_trailtoshadow_wake - (Added color)
Code

Added an answer, b/c that's the only way I've found to do code blocks. When running the example time ends up in the namespace because it's globally defined, but trackid doesn't; it's local to the d, track1 and track2 objects. You do call d in the initial ggplot() for p2, but then for geom_sf, you use area as the data. d is a tibble and if you want to refer to it's components, you either have to do it explicitly, as in d$trackid or through %>% when you can use the bare name.

I don't think that's correct.transition_componentstakes unquoted column names just likeaesinggplot. Also, if it was a matter oftrackidbeing undefined then the first animated plot wouldn't work, but this does: p <- ggplot(d, aes(lon, lat)) + geom_point() + labs(subtitle = 'Date: format(frame_time, "%b %e")') + transition_components(trackid, time) + shadow_trail(distance = 0.01, size = 0.3) animate(p, 100, 20)

d in the first animation works because it sets the data and the + arguments don't change it, so there's no need to quote "tracked." "Time" is already global.

I'm not sure what you mean.
trackid is defined in d. It's 1 for the first 100 rows and 2 for the second 100 rows. It's undefined in area, but then again so is time.– Corned Beef Hash Map

I don't think that's correct.
transition_components takes unquoted column names just like aes in ggplot. Also, if it was a matter of trackid being undefined then the first animated plot wouldn't work, but this does: p <- ggplot(d, aes(lon, lat)) + geom_point() + labs(subtitle = 'Date: format(frame_time, "%b %e")') + transition_components(trackid, time) + shadow_trail(distance = 0.01, size = 0.3) animate(p, 100, 20)– Corned Beef Hash Map

gganimate is not on cran, otherwise a great MWE. Could you add a comment with the devtools::install code? Just as speculation, where do the arguments to transitions_components come from? It seems you would need an sf object with a time series of centering points.

@RichardCareaga Totally forgot gganimate isn't on CRAN - thanks for the reminder! I think the arguments to transition_components are similar to arguments to aes, that is unquoted column names. In transition_components, they're the grouping and timestep variables, respectively. But I don't want the geom_sf to animate. I just want it there in the background. Not sure how to indicate it should be a static layer.
