Plotting "N/A" year when no values for that year exist

[jzadra]

There are no NA values in the dataset, however this is plotting an N/A year.

As a workaround for now, you can use the vcGroupingColumnNames argument, rename your column to Year from year.

This happens because https://github.com/AtherEnergy/ggTimeSeries/blob/a6233974af05e2cea3535c17d47082f1dc7fef2e/R/ggplot_calendar_heatmap.R#L98 adds NAs to the year column.

That bit of code is required because the lines separating the days, weeks, etc. are also drawn as part of the plot and they need to know which year, etc. they need to fall in which is why I calcualte year inside the function anyway. I confess, this isn't the most friendly or best written of functions.

I can think of some ideas to help make this more flexible -

• Allow a choice of colour, transparency for missing values.

• Allow a choice of layout for the facetting.

Any others you can think of?
