Stories about crops and statistics (plus coding)
First, let’s create a dataset. and observe the different data formats of each value. I have two sets of yield data: one in character format (yield column) and the other in numeric format (yield1 column). How to convert missing value to 0 when data is numeric? When data is numeric (yield1 column), and if there … Read more
When we draw regression lines for a group, they are usually of the same type, such as simple linear regression. Here is an example using yield data for different nitrogen rates per genotype. Then, the regression graph for each group would be shown below. I think it would be better to show the quadratic regression … Read more
When data is divided into two separate datasets, it needs to be combined into a single column. Using R, we can simply combine the two datasets. I will create a simple dataset. Now I will combine these two datasets into one. 1) using data.frame() To explain the below code simply, we are using the function … Read more
