Mean values and standard deviations (SD) can easily be plotted using the ggplot2 package in R. The same approach can also be used to plot the means and confidence intervals. In that case, you plot the lower and upper confidence limits instead of the mean-SD and mean+SD respectively. First, we compute the means and standard…
When presenting data on a plot, it is sometimes useful to also show a table with the actual numbers next to the plot. In some cases (e.g., mean profile plots and forest plots), the x-axes or y-axes of the individual plots/tables need to align with each other. There are several methods in combine plots and…
The Ggplot2 package can be used to create a bar graph with error bars. The geom_bar() function can be used to create the bar graph, and geom_errorbar() function can be used to add error-bars on the bar graph. We will use the dummy dataset (d_apples) below to create an example of a bar graph with…
