I cannot see how you get that code to run. It certainly does not on my machine and some of the manipulations don't make any sense as far as I can see. I changed variable and data.frame names so I would not have to type so much and read in the data with the "stringsAsFactors = FALSE" option. I then parsed the dates (called 'known' in my data.frame) using the package "lubridate" dat1$mydate <- dmy(dat1$mydate)
My resulting data.frame called dat1 is presented in dput() format below. Do I understand you correctly in that you want the NA values plotted as "white" and the outline on the tiles in black? In any case as my first steps here is a revised program to just get the tileswith no effort to get the outline or change the colours of the fill.
