I guess it maybe a silly question, but I have spent several hours reading help and googling and still could not find the missing labels for x axis ticks. Or tick marks? Anyway, I mean, the year/month names along the x axis. :)
With the following codes, I got charts exactly I want. Except that there is no label for x axis ticks. There are ticks line indeed .
I guess maybe there are something wrong with the par() of my R. But I just cannot figure out from reading the help(par). Indeed, if I use the plot to draw some chart for simple data, which plot maybe not the plot.xts I guess, there are tick labels for x axis.
Would you please tell me where could I find those tick labels for barChart?
require(quantmod)
getSymbols("AAPL")
barChart(AAPL)
