Making plots with binary predictor

Hello everyone! I'm kind of new to RStudio and I am using it for my dissertation project. I'm almost done with it, the only thing I need is some pretty plots :slight_smile: I have tried and tried but I have not accomplished anything. Does anyone have any suggestions about how to build a meaningful plot? I understand that I should use the function predict() but I am still not sure how.. most examples I found had the binary variable as response, not predictor as I do.

Many thanks!
(i do have the package ggplot despite what the reprex says)

# my data frame - rainfall_binary is numeric even tho it is a binary

df <- data.frame(
  VH_average = c(-18.4527033816948,
  rainfall_binary = c(1, 1, 1, 1, 1, 1, 1, 1, 1, 1),
  temp = c(4.05, 4.05, 4.05, 4.05, 4.05, 4.05, 7, 7, 7, 7)

# make GLM

GLM.REPREX <- glm(data=df, VH_average~rainfall_binary+temp)

Just to clarify, the package is called ggplot2

df$predicted <- predict.glm(GLM.REPREX,
            newdata = df )

would add a column that shows what your model predicted.

As far as graph goes, you should think about what information it is you are trying to communicate to your reader....
