Hi, I'd suggest you use dotchart() instead of plot(). I believe this
is what you expected:
dotchart(value, time)

#I copy the previous data then in R dat=readLines("clipboard")
options(digits.secs=6)
tmp=unlist(lapply(dat,function(x){unlist(strsplit(x,"\\

tmp=matrix(tmp,ncol=3,byrow=TRUE)

#How can I show in the x axis the complete time values including the
decimals.
Thanks a lot
N.B.: I am running the lastest version of R and using it under Windows XP
