#I copy the previous data then in R dat=readLines("clipboard")
options(digits.secs=6)
tmp=unlist(lapply(dat,function(x){unlist(strsplit(x,"\\ +",perl=TRUE))[3:5]}))
tmp=matrix(tmp,ncol=3,byrow=TRUE)
tmp=cbind(paste(tmp[,1],tmp[,2]),tmp[,3])
time=strptime(tmp[,1], format="%Y-%j %H:%M:%OS")
value=as.numeric(tmp[,2])
plot(time,value)
#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
