Welcome
Welcome to rgraphs.com, a broad collection of templates to make the creation of graphs a lot quicker and easier using the r programming language. Our visualization tool of choice is ggplot2. However, other packages are also used when needed.
- Plot Means and Standard Deviations in R ggplot2
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… - Boxplot Without Whiskers Using R GGplot2
Two methods are presented below to create a boxplot without whiskers in the R GGplot2 package. The first method is used when the boxplot is… - High Quality Forest Plots in R GGPLOT2
A forest plot is a very efficient way to present the results of an analysis that compares two groups for several populations or subgroups. It… - Combine Plot and Table in R GGplot2
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… - Annotate with Geom_text in GGplot2
The function geom_text() can be used to annotate on graphs in GGplot2. Geom_text() uses data frames to annotate. Other functions such as annotate() can also… - How to Annotate on a Graph with R GGplot2
Functions such as annotate() and geom_text() can be used to annotate a graph in GGPLOT2. This article focuses on the annotate() function which uses data… - Bar Graph with Error Bars in R
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,… - Stacked Column Chart and Clustered Column Chart in R GGplot
Stacked Column Chart A stacked column chart also known as a stacked bar chart is a type of bar graph that stacks the categories of… - Forest Plot in R
Forest plots are useful when conducting meta-analyses, to visualize the results of multiple scientific studies in a single graph. Forest plots are also commonly used… - How to Create Dummy Data in R
What is a Dummy Data? Dummy data are used to simulate real data. In the absence of real data, dummy data can be used to… - How to Fix the Error: Mapping Must be Created by aes() in GGPLOT2
“Error: mapping must be created by aes()” is an error you would eventually run into if you frequently use GGPLOT2 to create graphs in R…. - Mean Profile Plot in R
A mean profile plot is used to visualize the evolution of a variable measured over time. In a previous, we used a dataset of blood… - Visualizing Longitudinal Data
Longitudinal data is data collected repeatedly from the same subjects or objects over a period of time. The data collection times may or may not… - How to Plot a Line Graph in R with GGplot2
A line graph or line plot is a type of graph typically used to visualize longitudinal data. Assume we had a longitudinal dataset consisting of… - How to Create a Cumulative Frequency Graph in R
The focus of this page is to create cumulative frequency graphs in R using the stat_ecdf() function in the ggplot2 package, and the survfit() function… - How to Create a Histogram in R
There are multiple ways to generate a histogram in R. The function hist() that comes in base R can be used to create a histogram,… - How to Create a Bar Graph in R
Bar graphs, also known as Bar charts, are one of the most commonly used methods of visualizing grouped data. The length of each bar represents… - How to Create a Scatterplot Matrix in R
A scatterplot helps you visualize the relationship between two variables. When there are more than two variables and you would like to visualize the relationship… - How to Add a Regression Line to a Scatterplot in R
In a previous post, we described how to create a scatterplot plot in R. In the current post we will focus on fitting a regression… - How to Create a Scatterplot in R
A scatterplot (also known as a correlation plot) is a graph used to visualize the relationship between two variables. When looking at a scatterplot, one… - Make a Boxplot in R Using Already Computed Statistics
A boxplot is usually created from a continuous variable in a data frame. This is the preferred approach because it allows us to plot the… - How to Create a Boxplot in R
A boxplot (also known as box and whisker plot) shows the distribution of a continuous variable. It is a robust equivalent of the mean and…
