I have the following dataframe called df

I've got a barplot with 30 columns. I want to give the first 19 a set colour, with the remainder being a different colour. (See chart below).

I've tried making a vector of colours. I specified the names of the columns in the chart;

AMR_antibiotics <- c("AMIK", "GEN", "AMC", "AMP", "IMI", "P.T4", "FAZ", "FOV", "POD", "TAZ", "LEX", "CHL", "ENRO", "MAR", "ORB", "PRA", "DOX", "TET", "SXT", "AMOX", "AMPIC", "OXA", "PEN", "CEZ", "CPZ", "CEQ", "K.C", "MAF", "PIR", "ERY")

I then tried using the following code for assigning colours;

AMR_colours <- c(AMIK:SXT="steelblue", AMOX:ERY="coral3")

I would then end up adding AMR_colours into my ggplot code using scale_fill_manual (values = AMR_colours)

This hasn't worked, is it because trying to do this with the above code is completely wrong? I thought it would be an easier way rather than having to go through each column manually and repeating the same colours?

If this is completely wrong, any nudge in the right direction would be much appreciated! :)

Thank you!

I am using this theme material design https://gurayyarar.github.io/AdminBSBMaterialDesign/ to create a codeigniter application and I have a problem with the dropdown because it changes the code from this :

I'm trying to concatenate 3 fields to form a internal code and display it in the views:

I have 3 models:

• Category (size=2)
• Product (size=4)
• Serie (size=3)

And I want to display it in the form like this

Product Code: CAT-PROD-001

I don't know if i have to use a computed field or if exist anoter way to do this, because I was doing test with computed fields but can't reach the desired output.

Edit:

Now I'm trying to use a computed field with a onchange function to generate the value on the field
