For example, if you build many versions of a model to test different values for tuning parameters, you can create a heatmap to help identify the best model. That is, you can map a metric likeRMSEorarea-under-ROCto the “fill” aesthetic of your ggplot2 heatmap, and then use the heat...
The heatmaps are a tool of data visualization broadly widely used with biological data. The concept is to represent a matrix of values as colors where usually is organized by a gradient. We can find a large number of these graphics in scientific articles
A heatmap is basically a table that has colors in place of numbers. Colors correspond to the level of the measurement. Each column can be a different metric like above, or it can be all the same likethis one. It’s useful for finding highs and lows and sometimes, patterns. On to the...
What If I tell you that you can now build that Seaborn heatmap and pairplot in R using your RStudio? In this post, We will see how to make such Seaborn visualizations like Pairplot and Heatmap and for that matter, any Python code in R. Reticulate The Holy Grail here is ...

This example shows how to make a frequency table in R.For this task, we can apply the table() function to one of the columns of our example data frame:tab1 <- table(data$x2) # Make frequency table tab1 # Print frequency table # a b c d e # 1 3 2 1 1...
We will be using the base R programming language with no additional packages. This approach is especially useful when additional packages cannot be used or when you are looking for quick exploratory analyses. In other cases, you might consider usingggplot2, as covered in ourHow to Make a ggplo...
3D Plots built in the right way for the right purpose are always stunning. In this article, we’ll see how to make stunning 3D plots with R using ggplot2 and rayshader.
Now you can enter the data you want to use in R. Excel data validation To make an easy color-coded calendar, I’ll use the ggplot2 library and the ggcal package by Jay Jacobs on GitHub. I’ll also load dplyr, because I almost always end up using dplyr, whatever I’m doing; ...
I am trying to make a legend for my data that would reflect bar colours. When I add “col = status” it adds the legend but with dark grey colour inside. Any help would be appreciated? The code I am using is: p1 <- ggplot(d1, aes(x= reorder(gene, -fold_change), y= fold_ch...
