Hi!
I have problems with labeling x axis while plotting time series data. I have
40 monthly measurement. One period lasts 4 months. I'd like to have 40 ticks
on x axis (10 larger, the rest smaller) and labels just at the beginning of
each period, just like in the image
<http://r.789695.n4.nabble.com/file/n4660465/2221.jpg>
My code leaves x axis empty:
data <- read.csv(file="CSV files/Komen.csv", head=TRUE, sep=";")
dataTimeSeries <- ts(data, frequency=12, start=c(2000,4))
dataTimeSeries

require(graphics)
plot.ts(dataTimeSeries, xaxt="n", xlab= "Perioda", ylab= "Opazovane
vrednosti", type='l', col='red')
axis(side=1, at=seq(1,40,4), labels=seq(1,10,1))
Thanks in advance for any help!
Have a look at what
par("usr")
gives to see that your "at" setting makes no sense.
