R - How can I change date format when I plot an xts & zoo object?

Question

I am wondering how I can change date format.

The code I am working on is following:

library(quantmod)
getSymbols(\"AAPL\")
price_AAPL <- AAPL[,6]
         


        

Answer 1

With xts, you can use major.format directly.

plot(price_AAPL, main = "The price of AAPL",major.format="%b-%d-%Y")

However, you should know that zoo plots are generally more flexible.

plot.zoo(price_AAPL, main = "The price of AAPL", xaxt="n", xlab="")
axis.Date(1,at=pretty(index(price_AAPL)),
            labels=format(pretty(index(price_AAPL)),format="%b-%d-%Y"),
            las=2, cex.axis=0.7)
