I am using R to read from an excel(csv) file. Within the excel file

This is really an Excel question, rather than an R one. You need to
format the data in Excel so that it gets output to the CSV properly.
I tired separating the time and date using the function below and
then plotting again which fail to read properly
=TEXT(B2,"hh:mm:ss") and =TEXT(B9,"mm/dd/yyyy")
As I said, it's an Excel question.
The R script am using is
plot.time_vs_id<- function(start,end){
setwd("C:/Documents and Settings/terry/Desktop/r_stuff")
x=read.table("MAV.csv",header=T, sep=",")
plot(x$time[start:end],x$packet_id[start:end],ylab="Packet ID",
xlab="Time", type="p")
}
and
plot.hov_Points <- function(start,end){
setwd("C:/Documents and Settings/terry/Desktop/r_stuff")
library(rgl)
t=read.table("MAV.csv",header=T, sep=",")
plot3d(t$time[start:end],t$packet_length[start:end],t
$date[start:end], main="potential", xlab="time",
ylab="length",zlab="date", type="p")
}
How can i get R to properly display the time in my graphs
Thanks
