I have a dataframe of 60 observations and 13 variables. I am using ggplot to produce plots of all variables against just one variable in the dataframe (in my case its the second column in my dataframe, let's call it df_col2)
I have melted the dataframe and set key variable to be df_col2.
I can produce plots successfully with the following code:
melted_df <- melt(df, id.vars = "df_col2") ggplot(melted_df, aes(x = "df_col2", y = value))+ geom_point()+ facet_wrap(~variable, scales = "free_y")
Next, I want to colour the points on each plot by a particular variable in another column, in this case the third column in my dataframe.
Is it possible to do this with 1) a melted dataframe, and 2) using facet_wrap?
Any help much appreciated.
