[R] read.csv help

[Rainer Schuermann]

Can you explain a little more?

I have created a small CSV file following your pattern which looks like this in a text editor:

A,B,C,D,E
65,68,71,74,77
67,71,75,79,83
69,73,77,81,85
71,77,83,89,95

When I load it into R with
> x <- read.csv( "a.csv" )

I get this which I think is what you would expect:
> x
   A  B  C  D  E
1 65 68 71 74 77
2 67 71 75 79 83
3 69 73 77 81 85
4 71 77 83 89 95

with
> rownames( x )
[1] "1" "2" "3" "4"

Here is the dput version:
> dput( x )
structure(list(A = c(65L, 67L, 69L, 71L), B = c(68L, 71L, 73L, 
77L), C = c(71L, 75L, 77L, 83L), D = c(74L, 79L, 81L, 89L), E = c(77L, 
83L, 85L, 95L)), .Names = c("A", "B", "C", "D", "E"), class = "data.frame", row.names = c(NA, 
-4L))

What is different with your data?

Rgds,
Rainer
