Question

我想用gganimate制作动画情节。当我尝试渲染动画时，它会显示以下错误消息：

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

这是我要复制的代码。我正在使用R 3.6.0

library(gganimate)
library(magick)
library(dplyr)
library(animation)
library(tidyverse)
library(patchwork)
library(animation)
library(sp)
library(raster)
library(rgeos)
library(gifski)

planning_summary <- read.table(text = "
'Status'                        'Status Summary'

REPD <-
  REPD %>%
  merge(planning_summary, by.x = "Development Status (short)", by.y = "Status") %>%
  mutate(date = lubridate::dmy(`Planning Application Submitted`),
         year = lubridate::year(date),
         `Installed Capacity (MWelec)` = as.numeric(`Installed Capacity (MWelec)`))

animate(p, length = 15, width = 700, height = 400)

Answer 1

您加载了很多软件包，这些软件包也可能具有覆盖gganimate的动画功能

尝试

gganimate::animate(p, length = 15, width = 700, height = 400)

动画错误：无法为签名“ gganim”找到函数“动画”的继承方法
