Hi, welcome to R and RStudio,
It is almost impossible to do anything helpful from a screenshot. We really need your actual code and some sample data.
Have a look at
A minimal reproducible example consists of the following items:
A minimal dataset, necessary to reproduce the issue
The minimal runnable code necessary to reproduce the issue, which can be run
on the given dataset, and including the necessary information on the used packages.
Let's quickly go over each one of these with examples:
Minimal Dataset (Sample Data)
You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue.
Let's say, as an example, that you are working with the iris data frame
#> Sepal.Length Sepal.Width Petal.Length Petal.Width Species
#> 1 5.1 3.5 1.4 0.2…
for some suggestions.
Also, very simple and very effective way to supply some data is to use the dput() command.
and then simply copy the output and paste it here. If you have a very large data set then a sample should be fine. To supply us with 100 rows of your data set do
dput(head(mydata , 100))
where mydata is the name of your dataframe or tibble.
