The expression has b[1] and b[2] while start has b[2] and b[3].

The expression needs a different form, for example:

#   fit<-nlrob(y ~ x1 / (1+ b[1]*x2^b[2]),data = xx, start =
#   list(b[2],b[3]))
   fit<-nlrob(y ~ x1 / (1+ b1*x2^b2),data = xx, start =
   list(b1=b[2],b2=b[3]))

This "works", though I have no idea if the results make sense.

Dear all,
I would like to ask you if there are any gps libraries.


I would like to be able to handle them,
-like calculate distances in meters between gps locations,
-or find which gps location is closer to a list of gps locations.

Is there something like that in R?

I would like to tthank you in advance for your reply

Regards
Alex

I would like to have a relative x-axis in r. I am reading time seris from
an excel file and I want to show in a plot and also I want to have a window
which moves over the values.

My aim ist to see which point belongs to which time(row number in excel
file). i.e I am reading from 401th row in 1100th column in excel file and
my window length is 256. here is my code:

#which column in excel filespalte<-1100
#start row and end row
start<-401end<-600

window<-256
n<-1

wb <- loadWorkbook("D:\\MA\\excel_mix_1100.xls")
dat <-readWorksheet(wb, sheet=getSheets(wb)[1], startRow=start,
endRow=end, startCol=spalte, endCol=spalte,header=FALSE)
datalist<-dat[seq(1, length(dat[,1]), by = 2),]
datalist<-matrix(datalist)while(1+window<=length(datalist)){
  kd<-matrix(as.integer(datalist[n:(n+window-1),1]))
  Sys.sleep(0.2)
  plot(kd,type="l",col="blue",xlab="Rohdaten",ylab="values",xlim=c(start+n,start+n+window-1))
  n<-n+1}
