Enhancing Visualizations: Manipulating Color and Shape in R with Two Variables

Enhancing Visualizations: Manipulating Color and Shape in R with Two Variables

I have one dataset as below. Now, I’ll create a regression graph between grain number (GN) and average grain weight (AGW). I distinguished genotypes with different colors, and now I want to differentiate resistance (yes and no) using distinct shapes. Therefore, I’ll be changing the shape representation from genotype to resistance. However, the color is not currently applied to the legend. I aim to apply the provided color to the legend, and additionally, assign colors to represent different levels of…

Performing Regression Analysis in R with Variables in the Same Column

Performing Regression Analysis in R with Variables in the Same Column

When analyzing regression, we typically assume that two continuous variables are situated in separate columns, allowing us to easily designate them as x and y. However, in many cases, data is organized vertically, and variables of interest are found within the same column. This vertical structuring is, in fact, the fundamental data arrangement when conducting data analysis. Now, let’s delve further into the discussion by examining the dataset. Let’s proceed by uploading the dataset.” This data pertains to iron content…

Equivalent Functions: IF function in Excel vs. ifelse() in R

When working with Excel, I believe you use the IF function from time to time, especially when categorizing values. The IF function is particularly useful for this purpose. Here is one example. I want to categorize organic matter (%) by unit 1.0. This process involves converting numeric variables to categorical variables. To achieve this, I have used the IF function as shown above. Then, you can categorize organic matter in the F column as shown above. Now, my next question…

Converting Rows to Columns in R: A Guide to Transposing Data (feat. pivot_wider and pivot_longer)

Converting Rows to Columns in R: A Guide to Transposing Data (feat. pivot_wider and pivot_longer)

When data is arranged, it can be structured either vertically (row-based) or horizontally (column-based). The choice depends on your preference for organizing data. However, when running statistics, data should be arranged row-based, as variables need to be in the same column. On the other hand, when calculating per variable, it is much easier to organize data column-based, allowing for simpler calculations. Regardless of the approach, well-organized data is essential, and the ability to restructure data is a valuable skill. Today,…

The Science of Apical Dominance: Why Topping is Critical for Hemp Plants?

The Science of Apical Dominance: Why Topping is Critical for Hemp Plants?

In hemp cultivation, “topping” refers to the process of selectively cutting off the upper portion of the plant during its vegetative (growth) phase. This practice holds a central and essential role in plant training, as it encourages horizontal growth and optimizes light utilization, resulting in increased yields. When a plant is topped, the two auxiliary buds located just below the cut site develop into full-fledged branches, often taking on a Y-shaped structure. These secondary branches can also be subjected to…

Early Hemp Growth: A Vertical and Horizontal Stacking of Leaves

Early Hemp Growth: A Vertical and Horizontal Stacking of Leaves

In the early stages of growth, hemp plants tend to exhibit a pattern of stacked leaves, both horizontally and vertically. This growth pattern is characterized by leaves arranged in pairs at regular intervals along the stem, and as the plant grows, these pairs of leaves may be found at different vertical levels on the stem. This phenomenon is a typical part of the plant’s vegetative growth phase, where it is actively developing its leaves and stems. As the plant matures,…
