I wonder if it is better to work with the dates (1983Q1, 1983Q2,.....) directly? If I want to write a loop, say, to conduct some computation from 1983Q1 to 2011Q4, the only way I know is to convert the dates to the ordinal indices, 1, 2, 3...... Can we work with the dates? Is there any built-in equality that provides the computation like 1983Q1 +1 equals 1983Q2? In EViews, it is easy to do that. We can let %s run from 1983Q1 to 2011Q4, and he knows t...

R help, I would like to change the labels of my tick marks on the x-axis, and I am having difficulty understanding how. Basically, my current axis labels are: 0, 50, 100, 150, 200, and I would like: 1962Q1, 1974Q2, 186Q4, 1999Q2, 2011Q4. With all respect to generality, could you please simply tell me the code to achieve this in the context of this problem? I learn programming by example and will not be able to understand this: ltext(x, y = NULL, labels = seq_along(x), col, alpha, cex, srt = 0, lineheight, font, fontf...

Hi, I have the panel data of income statement of several banks. The date 9803 means 1998-Q1, 9806 means 1998-Q2, etc. I transform the date code to 1 (for 1998Q1), 2 (for 1998Q2), ...., 16 (for 2011Q4) where 1, 2, .... are placed in Col1. Now the income statement of a specific quarter is actually the accumulation from the beginning of the year. For example, the cost data of 1999Q3 is the cost from January to September 1999. Now, to find the cost in 1999Q3, I need to subtract the data of 1999...
