R cheat sheets: S3 and R5

I have added a couple of cheat sheets. Both are on object oriented programming under R: one on S3 and the other on R5. (I will probably get another lecture for calling reference classes R5, but who cares).

As always, if there are any errors, please let me know. I am constantly updating these cheat sheets as my understanding expands in respect of R's deeper mysteries.

Soft jobs data

The ABS released the October monthly labour force survey results. The unemployment rate was essentially steady at 5.4 per cent. Given yesterday's presidential election, I thought I would bring an electoral hue to today's charts.

The month-on-month change figures are pretty much steady as she goes. But the through the year statistics show a significant jump in unemployed persons.

This is becoming a longish period without healthy growth in the number of employed persons (certainly longer than the GFC).

The monthly hours worked continue to flat line/decline slightly. Over the last 12 months, the number of people in a job has risen slightly and the total number of hours worked has fallen slightly. All-in-all, these statistics suggest a soft labour market.

By gender: it is worth noting that the trend male rate is over the female rate. Arguably, since the 1990s, the male rate is higher than the female rate when the labour market is soft and lower when economic times are good.

By State - with clear unemployment rate trend increases in the low rate states in the last chart below.

House price index

Today the ABS released the latest House Price Index (HPI) data (for the September Quarter). Let's start with the national growth charts for established and project homes.

And on to the capital cities.

If we consider established house prices in the next chart: Although the slump minima in growth in 2011-12 was similar to that for the 2008-09 global financial crisis (GFC); the slope of the current exit trajectory is much shallower than the exit from the GFC.

And the actual indices.

Today's release also included capital city price and volume data to March 2012.

Retail trade

Today the ABS released the September monthly and quarterly retail sales results. The latest monthly figures look steady. The cafe/restaurants sector is slowing a little (but still growing at a healthy pace). WA is still the stand-out growth state. Tasmania is still trailing.

On the quarterly statistics, the implicit inflation statistics for the latest quarter may give some cause for the RBA to stop and think (although the through-the-year figures are still very low).

R environments, frames and the call stack

Another cheat sheet. This time on R environments, frames and the call stack. At the time of writing, it was the last one in the Google documents directory.

Like with my other cheat sheets, please let me know if there are any errors in this one. I am constantly updating the cheat sheets as I find subtle (and sometimes, not-so-subtle) errors.

My cheat sheet on reference classes is almost finished, so it might be the next off the production line.

Update:  I reorganised the cheat sheets so that they are now classified basic, intermediate and advanced.
