[R] help

[Anna Olofsson]

Thank you! The c was missing. I don't know if it's ok to continue on this
thread, but I also had another question about reading data. I have this
file containing 3 columns and 19 rows. 

0	0.96	0.21	
0	0.45	0.4
0	0.87	0.1
0	0.56	0.04
0	0.57	0.04
0	0.2	0.7
0	0.45	0.43
0	0.35	0.21
0	0.75	0.56
1	0.63	0.43
1	0.95	0.32
1	0.42	0.2
1	0.12	0.05
1	0.56	0.06
1	0.34	0.3
1	0.1	0.7
1	0.11	0.75
1	0.2	0.21
1	0.95	0.37

I tried to read it into R, but I'm not exactly sure exactly what to use as
input. This is my input line using read.table:

data1 <- read.table(file = "filename.txt", header=FALSE, col.names =
c("class", "P", "1G"))

but in the output I get an X infront of "1G", which disappears when I run
it with the name 'G' instead of '1G'. Am I not allowed to use numerical
values? 

Best,
Anna
