Now I want to plot y on a Secondary "Y-axis" on same I think you are lost a bit in plotting let's x be x<-rnorm(10) and y<-x*10 then gives you x values on y axis and x axis is 1:10. You can put another values y on the same plot but only if you give them space before plot(x, type="l", ylim=range(y)) points(y) but it is probably not what you want. If you want to plot time series to get time labels on x axis then Gabor's solution would be perfectly valid. Or you can convert your date (which is probably factor) to real time. > tab=read.table("clipboard", header=T) > tab date price 1 1-Jan-02 4.880375 2 2-Jan-02 4.879843 3 3-Jan-02 4.884013 4 4-Jan-02 4.880375 5 5-Jan-02 4.874968 6 6-Jan-02 4.875426 7 7-Jan-02 4.874663 8 8-Jan-02 4.875350 9 9-Jan-02 4.888242 10 10-Jan-02 4.889522 11 11-Jan-02 4.887111 tab$newdate <- as.POSIXct(strptime(tab$date, format="%d-%b-%y")) > str(tab) 'data.frame': 11 obs. of 3 variables: $ date : Factor w/ 11 levels "1-Jan-02","10-Jan-02",..: 1 4 5 6 7 8 9 10 11 2 ... $ price : num 4.88 4.88 4.88 4.88 4.87 ... $ newdate:'POSIXct', format: chr "2002-01-01" "2002-01-02" "2002-01- 03" "2002-01-04" . plot(tab$newdate, tab$price) what is what you may want without explicit need for secondary y axis.
