I was wondering how I could plot more tick marks when plotting time on the x-axis.

Basically, a time equivalent to pretty. Pretty obviously doesn't work so well with times, as it uses factors of 1,2,5 and 10. For time one probably wants e.g. hours, half hours, ...

plot(as.POSIXct(x,origin="1960-01-01"),y,type="l",xlab="Time")

gives really too few and widely spaced tickmarks.

zoox<-zoo(y,as.POSIXct(stats$Time,origin="1960-01-01"))
plot(zoox)

gives the same.

Thanks
