I have data on results of surgical operations:

• date of operation (in YYYY-MM-DD format)
• result of operation (0 for successful operation, 1 for unsuccessful operation)

I need to

• plot a learning curve
• get the data on current performance quality

The question is:

• What is the way to achieve this in R (with ggplot2 if possible)?

• Is $\dfrac{successful}{total}*100\%$ will be sufficient statistic for this case or something more advanced is usually required?

I have data on results of surgical operations:

Date is usually used only for case ordering. I need to

• plot a learning curve. (I had found that the resulting curve called cumulative average.) x should be the number of cases y - probability of failure (usually decreases).
• get the data on current performance quality
