Your mileage may vary, but again, be prepared to be flexible. E.g., although GIF is a very exportable and transportable format, and therefore ideal for many situations, I found that animations with more than ~500 source graphs just didn’t compile. Animation works exceptionally well when smaller numbers of individual graphs are being compiled, but as the number of individual graphs grows, so does your likelihood of hitting a problem.Things may also not work as well you’ll need to be prepared to be flexible with your animation formats and graph layouts. Because there are external programs involved (e.g., SWF Tools, ImageMagick, FFmpeg), the setup for this package is slightly more difficult than the average package and things will likely seem less polished than normal.The saveGIF() function call below illustrates the generic format for each of the calls: saveGIF( #Add letter on graph r how to#In most scenarios, however, you’ll want to create your own animations, so let’s look at how to do that.įirst, there are several different formats in which you can create your animations – GIF, HTML, LaTeX, SWF and mp4. The examples are of varying complexity ranging from a simple coin flip simulation to illustrations of mathematical problems such as Buffon’s needle problem. Here is how the codes work: library(gapminder) #to load the gapminder data library(agricolae) #to run teh posthoc lsd test library(ggplot2) #for visualization library(dplyr) #for data wrangling # install.packages(“remotes”) #just to give a good lock to the bar plot remotes::install_github(“coolbutuseless/ggpattern”) library(ggpattern) #however this library (ggpattern) has few limitation, we will discuss later #our model model_1 % group_by(year) %>% summarise(Mean = mean(lifeExp), SD = sd(lifeExp)) %>% left_join(lsd_test_df, by = c(“Mean” = “lifeExp”)) %>% ggplot(aes(factor(year), Mean)) + geom_bar_pattern(stat = “identity”, aes(pattern = year)) + geom_errorbar(aes(ymin = Mean - SD, ymax = Mean + SD), width = 0.5) + geom_text(aes(label = groups), vjust= -9.9) + theme_classic() + labs(x = “year”, y = “mean life expectancy”, fill = “year”) + scale_y_continuous(expand = c(0, 0), limits = c(0,85)) + theme(legend.The package installs out-of-the-box with several animations that are tailored for instruction. Does the year affect life expectancy? We ran ANOVA and found year has a significant effect on life expectancy, which can be explained as the year passed, improvement in medical sciences has significantly increased the life expectancy of people. We will run an ANOVA using the gapminder data to see how life expectancy has changed over the years. Note: I will use the “gapminder” dataset for this. I will teach you how to do the same thing in facet_wrap or in multiple sub-plot options. (minimizing the errors you could land into) I will teach you how to add error_bar and LSD letters to your bar plot using R packages. If you are like me, who was confused about adding those letters to the plot (bar plot) for publication purposes, this post can help you. Your result output has a bunch of alphabets and groups. Now you want to run a post-hoc mean comparison to see significant mean differences among each treatment. If you are doing experimental design or hypothesis testing, you found a significant treatment effect on your response variable through ANOVA (analysis of variance). How to add LSD letters in geom_bar plot in R?
