Hi all

I have a data set of the following format.

     0  0.7087872E+06
     5  0.7087872E+06
    10  0.7087872E+06
    15  0.7087872E+06
    20  0.7087872E+06
    25  0.7087872E+06
    30  0.7087872E+06
    35  0.7087872E+06

I was trying to read in this file and plot it.

leg16<-read.csv("wwleg16.ttn",sep=" ", dec=".", header =F)

Why would you use read.csv when the file is not comma-separated? If you get nothing it is probably because you have not put the file in your working directory.

This is what I get (because of every space is interpreted as a separator.)

> leg16<-read.csv("ttest.tnn",sep=" ", dec=".", header =F)
> leg16
  V1 V2 V3 V4 V5 V6       V7       V8
1 NA NA NA NA NA  0       NA 708787.2
2 NA NA NA NA NA  5       NA 708787.2
3 NA NA NA NA 10 NA 708787.2       NA
4 NA NA NA NA 15 NA 708787.2       NA
5 NA NA NA NA 20 NA 708787.2       NA
6 NA NA NA NA 25 NA 708787.2       NA
7 NA NA NA NA 30 NA 708787.2       NA
8 NA NA NA NA 35 NA 708787.2       NA

Use read.table instead. (and it will only read it if if is in your working directory.)
> leg16<-read.table("ttest.tnn", dec=".", header =F)
> leg16
  V1       V2
1  0 708787.2
2  5 708787.2
3 10 708787.2
4 15 708787.2
5 20 708787.2
6 25 708787.2
7 30 708787.2
8 35 708787.2



But leg16 holds all NA's.

How can I read this properly as two numeric values?

I can do this in Excel, but want to learn to do in R also. Could anyone
of you help me with this?

Regards

Rose
