gganimate unable to call ImageMagick correctly, possible path error
<p>I  am trying to install gganimate in Windows 7. I have already added Path to ImageMagick and below are the codes I used in my attempt to install it.</p>

<pre><code>library(httr)
set_config(config(ssl_verifypeer = 0L))
library(devtools)
library(RCurl)
devtools::install_github("RcppCore/Rcpp")
devtools::install_github("dgrtwo/gganimate")
install.packages("gapminder")
library(gapminder)
library(ggplot2)
theme_set(theme_bw())
p &lt;- ggplot(gapminder, aes(gdpPercap, lifeExp, size = pop, color =continent,   frame = year)) +
geom_point() +
scale_x_log10()

library(gganimate)

install.packages("cowplot")
install.packages("animation")
library(animation)
ani.options(convert = shQuote('C:/Program Files/ImageMagick-7.0.3-  Q16/magick.exe'))
gganimate(p)
</code></pre>

<p>But I get the following error after I run the last line gganimate(p):
<a href="https://i.stack.imgur.com/IwAAe.png" rel="nofollow noreferrer">Error</a></p>

<p>The error is:</p>
