I have to search an answer for my problem.
I have to plot some hystorical data, nothing special ar difficult,
but I don't know haw to do to appear on the x axis the dates of my
data.
For example my database has records starting with 03th January 2001
but on x axis apear as label dates starting with 2nd January 1970.
What is the function for corrige my plots? I have been trying
funtions from the packages xts and zoo.
You didn't provide a reproducible example, so anyone who answers is just
guessing, but it seems likely that your
source data is not a time series.
You probably have a data.frame or matrix or similar, and when you use
plot, you're getting a forced index.
check the class of your input data to make sure that it is xts.
then plot (from zoo, xts, or xtsExtra) or chart_Series or chartSeries
(from quantmod) will work just fine.
