Using ggplots to create boxplotscombining data from two columns into one
The sample data I am using has two columns (AgeAtDeath and Sample_ID) which contain the variables I need to plot. I combined these two columns. I had already managed to create a boxplot with ggplot using the variables from only Sample_ID by way of subsetting the data into 'AD', 'Control', and 'Resilient'. When I added the fourth variable 'Exact90' from the merged columns, the code ran, showing that there were no errors, but there was no boxplot displayed for the 'Exact90' data? What could I do next?
