Hello, I have a dataset for 50 American states over 8 years. My variable of interest is dichotomous (0,1). There are some missing values which are entered as 'NA'.
I need to visualise the frequencies for this variable in a combined bar graph for each of the 8 years. I am unable to write the code which will give me a combined graph, while also excluding the 'NA' values.
Any leads would be helpful! TIA
