How do I get the plot in the attached format of time axis?. When I issue
plot(ts) I get a time series plot with tic only for years.


Hi Sudheer,
If your problem is similar to that answered last week "X axis label as months", you can follow the suggestion by the other Jim and then add a custom x axis. The problem is getting the axis labels aligned, and this function:

tsxpos<-function(x) {
  # make sure that there is a graphics device open
  if(dev.cur() == 1) stop("A graphics device must be open")
  plotlim<-par("usr")
  divlim<-ifelse(par("xaxs") == "r",0.04,0)
  xrange<-(plotlim[2]-plotlim[1])/(1+2*divlim)
  xstart<-plotlim[1]+xrange*divlim
  nint<-length(x)-1
  return(cumsum(c(xstart,rep(xrange/nint,nint))))
}

when called after creating the original time series plot will return the x positions for the time series (the "x" argument is for the time series object). You can then pass these values to the axis function in the "at" argument with your desired labels in the "labels" argument. This function has been added to the plotrix package and will appear in the next version.

Jim
