[Rd] need some help in plotting xy graph

Hi

 

   Dataframe    fdf contains

 

bin rate                                                         overlay

1   1   90 Assign First/cc _from_SN_53 RNC_20_to_SN_50 RNC_21_Success
Rate

2   2   93 Assign First/cc _from_SN_53 RNC_20_to_SN_50 RNC_21_Success
Rate

3   1   90 Assign First/cc _from_SN_50 RNC_21_to_SN_53 RNC_20_Success
Rate

4   2   94 Assign First/cc _from_SN_50 RNC_21_to_SN_53 RNC_20_Success
Rate

                 time

1 (04/01/08 16:02:30)

2 (04/01/08 16:07:30)

3 (04/01/08 16:02:30)

4 (04/01/08 16:07:30)

 

 

And then I write the following lines of code to plot a xygraph on a pdf
file 

 

 

  n <- length(unique(fdf$time))

  x <-sort(unique(fdf$time))

  y<-UTCsecs2chron(x)

 

 

  xscales <- computeTimeScales(y)

  yscales<-NULL

 scales<-c(xscales,yscales)

  ylab<-"session transfer rate"

  xlab<-"time"

 lgnd.txt<-levels(fdf$overlay)

 

 celnet.trellis.device(device="pdf", file="ravi_st.pdf",
width=10,height
= 10)

 

main<-"this is the first report"

 formd="rate ~ as.numeric(time)"

 print(

         xyplot(formula(formd),

           data = fdf, groups = overlay,

           type = "b", as.table = TRUE, cex=0.20,

           #subset = ok, commented to show breaks in graph

           main = main, xlab = "Time", ylab = ylab,

           scales = scales,

           key = simpleKey(text = lgnd.txt, cex = 3/4,

                  points = FALSE, lines = TRUE),

           page = function(n) annotate(opts$ann),

           sub = "",

           layout = c(1,1)

          )

 

       )

          

 

 

 

 "computeTimeScales" <-

function(z, rot=0)  ## z is a chron object

{browser()

   ## how many days do the data span?

   n.days <- ceiling(diff(range(z, na.rm = TRUE)))

 

   ## compute x ticks, pretty labels

   x <- as.numeric(z)

   r <- range(x, na.rm = TRUE)

   at.x <- seq(from = r[1], to = r[2], length = 7)

   two_digits <- function(x){

      x <- paste("0", x, sep="")

      substring(x,nchar(x)-1)

   }

 

   ## heuristics: use hh:mm when range of data falls within one day,

   ## otherwise use MM-DD hh:mm.

 

   at.z <- chron(at.x)

   hh <- paste(two_digits(hours(at.z)), two_digits(minutes(at.z)),
sep=":")

   if(0){        ## hh:ss # this is commented as for more than one day
from/to time no date was printed

      at.lbls <- hh

   }

   else {              ## MM-DD\nhh:ss

      m <- month.day.year(at.z)

      dd <- paste(two_digits(m$month), two_digits(m$day), sep="-")

      at.lbls <- paste(dd, hh, sep="\n")

   }

 

   list(x=list(at = at.x, rot=rot, labels = at.lbls))

}

 

 

"celnet.theme" <-

function()

{

   celnet.theme <- canonical.theme("pdf", color = TRUE)

   if(tolower(.Device) =="png")

      celnet.theme$background$col <- "white"

   else

canonical.theme("pdf", color = TRUE)

      celnet.theme$background$col <- "transparent"

   celnet.theme

}

 

"celnet.trellis.device" <-

   function(device, file, width = NULL, height = NULL,...)

{

   ## analogous to trellis.device() -- this is just tailored to Celnet

   if(is.null(width))

      width <- 8

   if(is.null(height))

      height <- 6

   if(tolower(device)=="png"){

      if(missing(width)) width <- 72 * width

      if(missing(height)) height <- 72 * height

   }

   if(tolower(device)=="x11")

      trellis.device(device, width=width, height=height,
theme=celnet.theme())

   if(tolower(device)=="ps" ||
tolower(device)=="postscript")

      trellis.device("postscript", file=file,  color = TRUE,

         width=width, height=height, theme=celnet.theme())

   else

      trellis.device(device, file=file,

         width=width, height=height, theme=celnet.theme())

}

 

"annotate" <-

   function(str, ...)

   ## print a metadata message at the top-bottom of current trellis
display

{ else if(n==1){

      x <- 0.95

      hjust <- "right"

   } else if(n==2){

      x <- c(0.05, 0.95)

      hjust <- c("left", "right")

   } else if(n==3){

      x <- c(0.05, 0.50, 0.95)

      hjust <- c("left", "center", "right")

   }

 

   x <- unit(x, "npc")

   y <- unit(1.5, "lines")        ## at 0.5, 1.5, ... lines

 

   for(i in seq(along = x)){

      grid.text(label = str[i],

                x = x[i], y = y, just = c(hjust[i], "bottom"), ...)

   }

   invisible(str)

}

   n <- length(str)               ## one line per string

   if(n==0)

      return(invisible(str))

}

 

 

                                                     

 

 

But I did nt get any desired o/p on a file ravi_st.pdf

 

Desired o/p is

  Rate ~ as.numeric(time)

Group=overlay

Can any one tell how can I get the desired o/p

It would be more work to read in your data than I have time for. Could
you post it in a more convenient format? (The output of dput(fdf)
should be fine.)

[Rd] need some help in plotting xy graph

1) If you need some help,  *PLEASE* use the R-help mailing list.

2) Sending your e-mail more than once (you sent it 3 times!) to
   the same mailing list of hundreds of subscribers
   is considered very impolite.
